Copperhead14 Posted June 3, 2018 Report Share Posted June 3, 2018 (edited) My wife's 2014 Journey SE 2.4 liter had the check engine light come on recently. I pulled the codes and got P2305 and 2311. Cleared codes and they returned on next start up. Both codes were for Secondary resistance on Coil B (2305 no. 2 cyl ) and coil D (2311 no. 4 cyl.) The vehicle was purchased new in November 2014, and has 5300 miles. I found it improbable for and engine with less than 6K miles to have coil or plug issues, but I pulled the coils and checked resistance. All coils were reading the same resistance across terminals and from terminal to spark plug contact. The no. 2 and 4 plug resistance was lower than no. 1 and 3. I replaced the plugs with NGK Iridium gapped at 0.44. Still getting codes, 2305 and 2311, but engine runs fine, accelerates quicker with no hick ups. I did swap 1 and 2 coils as well as 3 and 4 coils to see if the codes changed. No change there. The vehicle is no longer under factory 36 month warranty. Any suggestions would be greatly appreciated.

lmoore1436 Posted June 4, 2018 Report Share Posted June 4, 2018 Sounds like you are going to have to take it somewhere to get it looked at. Engines aren't really designed to sit for extended periods of time, and it sounds like it hasn't been running much at all, the issue may be tricky to find. When an engine doesn't run much it causes issues everywhere, corrosion, seals, internal lubrication, buildup in fluids, etc. You said "Accelerates quicker" in your post.... do you mean that you noticed a gain in performance when you did change the coils? If so it could take some time for the code to clear. I'd recommend leaving the battery unplugged for a while (about 30 mins to an hour) to reset the computer. If that doesn't work then you should definitely take it to get looked at. jkeaton and OhareFred 1 1 Quote Link to comment Share on other sites More sharing options...
2late4u Posted June 4, 2018 Report Share Posted June 4, 2018 (edited) are you saying the journey is running fine now ,,except it is showing the codes? if so just use it as is and see if the codes will go away after some use................. .also i believe the 2.4 uses the copper plugs not the ones you used...keep us informed on what happens.

Copperhead14 Posted June 4, 2018 Author Report Share Posted June 4, 2018 My wife usually drives the car at least once a week for short trips ( less than 30 miles ). I always felt the car accelerated poorly, due to a small motor in a large vehicle. There was never any hesitation or misses. I kept the original plugs and I may reinstall them. I drive a 2008 Chevy HHR with a 170 hp 2.4 liter running iridium plugs (oem). I thought that would be an upgrade. Like I stated previously, the vehicle runs fine and acceleration seems smoother and quieter. I'll due some more driving with it to let it go through some start cycles and see what happens. Thanks for the feed back. Quote Link to comment Share on other sites More sharing options...
bramfrank Posted June 4, 2018 Report Share Posted June 4, 2018 An observation: The fact that you swapped the coil packs and the problem didn't follow the coils implies that the issue lies elsewhere - possibly some corrosion on the connectors at one end or the other of the wires connected to the coils or something in the ECU. 2late4u and OhareFred 1 1 Quote Link to comment Share on other sites More sharing options...
bfurth Posted June 4, 2018 Report Share Posted June 4, 2018 Use copper on the 2.4, not iridium. The Chevy EcoTec engine used iridium plugs. The only thing that EcoTec and the Chrysler World Gas Engine (the full name of the 2.4L in the DJ and many other Mopar vehicles) have in common is the displacement and the grade of fuel they use. I second the suggestion to disconnect the battery for 30 minutes while having the 1/2 and 3/4 coil packs swapped (you already replaced all four plugs - albeit with iridium). If the problem follows the coil pack, then you have your answer. If the problem stays where it is, I would think it's a wiring problem. If you get 4 new problems - rip out the iridium and replace them with copper, then test everything again. 2late4u and jkeaton 1 1 Quote Link to comment Share on other sites More sharing options...
Copperhead14 Posted June 5, 2018 Author Report Share Posted June 5, 2018 I had swapped the coils around with no change in codes. I disconnected the battery for 1 hour and no change in codes. I will reinstall the original plugs and clean connections at the coil with a plastic safe electrical contact cleaner. jkeaton 1 Quote Link to comment Share on other sites More sharing options...
OhareFred Posted June 5, 2018 Report Share Posted June 5, 2018 Can’t you clear the codes with the code reader you used to get them? See if an auto parts store will clear them for you so you can see if they return..... Quote Link to comment Share on other sites More sharing options...
Copperhead14 Posted June 6, 2018 Author Report Share Posted June 6, 2018 I cleared the codes with my code reader, but they come right back at start up. Put the original plugs back in and cleaned connectors at the coils and PCM. No change. Same codes. Took it for a ride and again, ran fine. I think I will try to put some miles on it this weekend and see if they clear on there own. Quote Link to comment Share on other sites More sharing options...
Hankster Posted June 6, 2018 Report Share Posted June 6, 2018 I found out the hard way that the 2.4l is very fussy on spark plugs. Put in the factory recommended plugs, check the bottom of the coils for carbon tracking in the rubber boots.
