Thanks to the advent of technology, just about every single part on your new Jeep JK Wrangler is wired up to a computer. And, if anything goes wrong with any one of these parts, your Jeep’s computer will make a note of it and/or even let you know about it by illuminating a Malfunction Indicator Light (MIL for short or ‘check engine’ light) or icons on your dash. Unfortunately, the MIL or other icons won’t tell you a whole lot other than the fact that your Jeep is having some kind of a problem and unless you take your Jeep into the dealership or have a OBDII reader handy, you’re pretty much out of luck, right? Wrong. As luck would have it, the JK Wrangler’s come with a Diagnostic Trouble Code (DTC) reader built right into the dash and you can access them by following the 3 simple steps below. Once you have the DTC code(s) in hand, check it/them against the list below and you will be able to find out exactly what problems your Jeep is having.

How to Read a DTCA DTC or Diagnostic Trouble Code is made up of 5 digits the first of which is one of the following letters:

B - Body
C - Chasis
P - Power Train
U - Network

The 2nd digit indicates:
0 - SAE
1 - MFG

The 3rd digit indicates:
1 - Fuel & Air Metering
2 - Fuel & Air Metering (Injector Circuit)
3 - Injection Systems or Misfire
4 - Auxillary Emissions Control
5 - Vehicle Speed Control & Idle Control System
6 - Computer Output Circuit
7 - Transmission
8 - Transmission

The last 2 digits indicate:
Fault (00-99)

Instructions1. To check your Jeep JK Wrangler’s DTC codes, simply insert your key into the ignition, turn it to the ‘ON’ position but do not start the engine. Then, push the key into the ignition cylinder and while holding it in, turn it to the ‘OFF’ position and then back to the ‘ON’ position (3) times straight making sure to end with it in the ‘ON’ position. It is important to keep pushing in on the key to prevent it from catching at the different positions along the way.

2. If you do step #1 correctly, all your dash lights will illuminate and your odometer will show up as a series of (6) dashes as shown in the pic to the left. If your Jeep JK Wrangler has any logged in any DTC’s, they will be displayed soon after the dashes appear. Write down the DTC(s) and check it/them against the list below to find out what they mean.

3. If your Jeep JK Wrangler has not logged in any DTC’s, the dashes on your odometer will be followed by the message ‘-done-’. Turn your key to the ‘OFF’ position and you will in fact be done.

Nothing came out on my dash except that annoying "check engine" light that keeps showing up on my dash even there's nothing wrong with the jeep. Also, I have used the AEV PROCAL module to reset the problem but it keeps coming back. Can someone help me with my concern. Thank you very much.:grayno:

You can try a hard reset by disconnecting your battery for a few minutes (10?). If that doesn't work you may have to take it to the dealership so they can plug it into their own computer to find the cause.

I did this this morning on my 12 2dr and it didn't work going from on to off either. It works going from on to acc and back 3 times. Try again but just the one notch instead of two. Unfortunately none had no code for why it's been temping between half and 3/4 on my gauge the past couple months, but checked and went straight to done. In glad however it wasn't having other problems. Don't mean to sound upset that it didn't pop out a few grand I need to spend in code fixes.

I just got my Superchips TrailDash from the mail and installed on my 2011 Jeep JK Rubicon. After setting up based on the Step-by-step instructions,
Immediately reached for the Diagnostics for the check engine codes option and finally got the reading of U1418 - Implausible right wheel Distance Signal, and P0420 - Catalyst Efficiency (Bank 1) readings. Is there any section here which I could interpret these error codes and trouble shoot the specific problems? Anyone? Thanks

anyone get this ?? Jeep went offline while driving, for what reason I do not know,,,,,I do know what the code entails, but why would it have dropped offline in the first place is unknown and while I was driving 65mph plus...any ryhmme or reason the jk would drop out of forward travel and the re engage or reset itself,,? anything come to mind...its showing no other trouble codes and no mil light....

We had this happen to our T&C where the dash re-set while driving. Since then I have learned a lot about how the CanBus operates and most techs hate it! Here is a short breakdown. The TIPM or fuse box is like a cross roads and handles most orders like fuel pump on, window down and such but is also pass through for like your dash display. The ECM and antilock break module go to the TIPM and have connections together. The BCM, body control module, go back to TIPM. There really is no rhyme or reason to it! An example I was given you get a code pointing at a wheel sensor problem. You check sensor wiring and can't find anything so you replace sensor. Still get code. Take to dealer and they do the same thing. Come to find out it is the anti lock break module but it could of been the TIPM also. When you have modules that have to pass commands through them but don't control anything with this command and this module gets a problem like a bad connection or chaffed wire you get codes that point no where! That is why techs will shot gun stuff like this when it may be just a connection!

OK with that all said I would re seat all the connections under TIPM. There are a ton of them. Just tip it forward after depressing lock tabs. There is lock tabs on each one then push locking arm forward to release each one. Look at each connector and make sure they are clean. If dirty blow out connector and also look for pins pushed back out of housing. If so pin was probably never seated so pin needs to be pushed into shell from the back till it seats or clicks in place. Look at harnesses to make sure none are rubbing or rubbed through. They are really packed underneath and make tight bends. Make sure to lock each one after re seating them.

Now go over to the ECM/PCM, electronic control module or programmable control module in front of brake module. Should be three connectors if manual transmission, four for automatics, and reseat all of these. You should hear a pop when you pull each one of these off. They seal very tight so make sure they are clean and sealing properly.

If this doesn't fix the problem you could also re seat connector on back of dash display. From there it could be a bad module or a bad connection on the two CanBus wires. This would entail chasing wires and a schematic of the system. I wish I had a good or easy explanation but these systems are very complex. I could be something as simple as maybe you put in an aftermarket radio and the module that was added to talk to CanBus, yes the communications ties through radio, has a loose connection. These two wires for CanBus are plus and minus and need a module to terminate each connection. If it opens up it is like pulling your network cable from your computer. If they get shorted or crossed bad things happen also. On a chevy you could pull each module then jumper the two wires for the CanBus to eliminate each module. But since Chrysler passes the CanBus through modules this may not work!

Try the simple things first like re seating stuff and look for the obvious like rubbed wires. If you find exposed wires seal them back up. Broken wires solder and cover with two layers of shrink tube. Did you just add or changes something? Did this system rest happen after a big bump? Is anything else occurring like whippersnapper going for no reason? What year jeep? The 07's had quite a few issues and have several differences with there sister models. Don't try to switch modules with a buddies jeep! He may not be yor buddy for long! This could make the module un usable.

Any questions let me know since I may have completely confused you!

jims68
09-13-2014, 02:16 PM
Forgot, lift + battery before doing ANY of the above things! This will ales reset the PCM and clear codes after about 15 minutes or just take + after finishing work and touch it to - before laying back down. This will drain the system down. Good luck.

Just tried to read the code as I had the 'MIL' engine light on... our 2013 JKUR w/ the 3.6 wouldn't show the bars or codes at first but kept playing with it and found that it worked with the combination of the 'ON' to 'ACC' (one click back, not two to 'OFF' as 'tinkering1' says above) three times at a faster pace worked for us. We found that the speed of the clicking for & back made a difference, a slightly slower pace didn't work but the faster did...either way....Thanks Eddie for providing this great info and the list of codes for us to use! :thumb: You rock :rock: !

I didn't see the code my Jeep threw along with P0133 O2 Sensor code, P0958. It took a while, but it turns out that P0958 will always remain in a ‘Pending’ status on the ECM since the transmission installed during my Hemi conversion was designed for a 2008 Jeep Grand Cherokee with the 5.7L Hemi with an automatic transmission that has a manually controlled shifter mechanism which allows the driver to ‘toggle’ through the transmission gears selectively. Since the JKU transmission does not have this capability, the computer is looking for a circuit that isn’t there. This won’t throw the ‘Check Engine’ light on, however. But, when another DTC is generated, the P0958 code will always be presented with the other code(s). In other words, disregard it.

While driving to Death Valley this morning my ESP and electronic throttle control light came on at the same time. The throttle response became a bit "jerky" I stopped and turned off the Jeep. When I restarted the jeep a few minutes later the lights were off and the Jeep ran fine. I drove into Pahrump and stopped at the AutoZone to have them read the codes and they were clear. Is this a weird anomaly or something I should have checked out by a proffesional?

I looked up the requirements to change out the valve. It seemed basic enough to do. But a couple weeks ago, the code cleared on it's own. So, for now, I'm just letting go. I haven't noticed any performance changes since it went off. Don't know what that may indicate.

If it was a hard code, light will come back on soon or would have already. If it doesn't, you're fine. It could be something as simple as a loose gas cap. You can also go to Autozone or Oreillys and they will scan OBDII engine codes for free.

Welcome to WAL.

Make sure your gas cap is tight. If it is and codes persist after clearing, replace the cap. Clear your AlGore codes and see if they come back. That's the easy way to diagnose it.

The proper and more expensive way is to run your tank down to half way, take it to the dealer and have them smoke test it for you. That will find the leak.

If it were me, I would start with the gas cap.

Crazy that this post is here...
My 2014 JKU has 30,250 miles on her and the Check Engine Light is on.....
I called the dealership on Thursday morning to schedule an appointment to get the AC compressor repaired and then as I was about to leave work Thursday night, I cranked my 2014 JKU and the check engine light came on. WTH!!
Ran the codes and got P0520.
Had to call the dealership Friday morning to add more work to be done.
Thanks for posting the codes, this helped me a lot in knowing what was going on with my jeep.
Now it's up to the dealership to get her squared away.👍🏻

I've changed batteries in two JK's 2011 & 2013, and had no codes like that. Sounds like there may be another issue. Hopefully someone else can chime in. Good luck!

Thanks. Finally got it to work, but showed no codes and MIL is still on. Any ideas other than disconnect the battery to do a reset?

Take it parts store most can scan for you and clear them I would do that before reset

Found a dealer to scan it for free with an OBD reader... evap code. Possible gas cap issue, but I don't think so. Anyhow, he cleared it and sent me on my merry way.

It's probably the same code mine is throwing - small evap leak. The mechanic who put my gears in told me there's a recall on the evap hose for a lot of these JK's and if so that's a covered replacement, warranty or not.

P0405 says egr position sensor low... has anyone else had this code and what was your fix... I'm gonna start with the wire harness and go from there really hoping I don't have to replace the egr valve itself ... I've been getting this code randomly about every other month sometime two months in between but no rough idle or stalling occurs any other symptoms I should look for

UPDATE: so since I've thrown this code I've started to get a ticking noise that's pretty loud on cold start and once it warms up gets a lil quieter at idle but gets louder as I drive and press the gas... could this egr valve be bad and be causing this...? I also changed the spark plugs and am changing valve cover gaskets as they have a small leak... also I've noticed that my engine does seem to get hot a lil more often than normal now to so the fan kicks on a lot any ideas ....?

Cleaned my throttle body the other day. Which was nasty. Took it for a test drive and the jeep went into limp mode. P2112, P2110, P0401 and P121c, unplugged the battery and it went away. But keeps coming back. Bad throttle body?

Did you prop the throttle body open with the key on by chance when you cleaned it?

No I took it off the motor, cleaned it and reinstalled it

My assumption was right. Changed the throttle body and she runs perfect!

All,
I have a 2008 Jeep Wrangler JKU:
6-speed manual; Dana-60 axles (5.38 ratio); 4-inch lift kit; 38-12.5r17 tires; Pypes Cat-back off-road exhaust; and OEM air intake (running K&N reusable air filter) – 125K miles on vehicle and stock motor. 12K winch is buried in SRC Pre-runner bumper – so no airflow restrictions.
Operating temps have never, ever been an issue – until I recently towed a trailer in highway summer conditions (100 degree ambient air) on Baker, CA grade (east and west bound), as well as, eastbound up to St George and beyond on I-15. Trailer is 2-axle , 14-foot enclosed - with 1000 lbs Harley as load (approx. 4500 lbs gross weight). Also, in idling/crawling in SW desert conditions – where fan stays on for extended periods of time in Lo-4.
In an attempt to improve the cooling system – using OEM only parts they offer in Middle Eastern countries for JKs, I have added the mechanical fan shroud, thermostatic fan clutch, and fan blade – which are installed over a stock electrical fan and slightly modified electric fan shroud (trimmed to fit inside new mechanical shroud and mount to same mounting points) as additional capacity during projected high heat events.
In the four days since I’ve had this new setup installed (Jun 24th), I have tripped P0128 and P2181 codes three times.
I replaced original coolant, hoses and thermostat (195 degree) with OEM parts one month (May 20th) before I pulled the trailer in summer conditions (2017 Memorial Day weekend – Baker, CA registered 103 degrees at 1pm when I past westbound on I-15). Have had absolutely no faults in the life of this vehicle (guess they don’t make them like this anymore, eh?)
I am not having an overheat issue, rather, it runs 30+ degrees cooler without any trailer loads – approx. 160 degrees on OBD scanner. If I let the jeep idle for over an hour, it will finally reach OEM operating temp (190+), and then cools right back down to approx. 160-170 when rolling 25+mph . I don’t get a code trip when I do that. It’s during cold starts in morning on commute to work, or, short trips to market when vehicle is not allowed to warm-up that the codes trip.
Can the ECM be sufficiently remapped to eliminate these code-tripping conditions?
Can I get a different Coolant Temp Sensor that tricks the ECM? Can I drill a bleed hole that directly hits the sensor tip?
Can I get a different thermostat that keeps the Coolant Temp Sensor reading the actual hot engine temps? (bleed-hole type, or, larger bleed-hole)
Does the electric fan switch also provide input to the ECM that would require relocation of the sensor to a location other than on the mechanical fan shroud (the electric fan shroud had the sensor less than 1-inch from radiator fins – new mechanical shroud has it almost 3-inches away from the radiator fins)? The mechanical fan interfered with leaving the sensor in the original location on the electrical fan…
This setup is absolutely awesome, and, FCA (then Mercedes) should have told the US EPA to go pound sand when they were forced to remove the dual mechanical/electrical fan setup for US consumer usage, but they didn’t.
What mods do I need to do to make this vehicle stop reporting such ‘false failure’ conditions?

Sounds like you've nailed down the cause. I would assume the ECM is indeed triggering the code due to the vehicle running too cool. If I were in your shoes, I would talk to a shop foreman or a helpful service writer at a local dealer and see if there is any reprogramming they can do. The only other thing that I think you could do, but may require some trial/error work is to wire a resistor in between the ECT sensor and ECM to trick the computer into thinking that it's receiving the right signal. Only issue with this would be when it's warmer, it may think the vehicle is overheating. Kind of a tricky issue. Other than the code, are there any other abnormal symptoms?

New PCM seemed to fix the issue after confirming the wiring was good between the PCM and coil pack
