hexnut Posted November 28, 2020 Report Share Posted November 28, 2020 My 2018 Dodge Journey is throwing the following codes at the same time: P0340, P0345, P0365, and P0390 I cleared them to be sure it wasn't a glitch. After several hours/miles of driving the codes came back. Seems odd to have two sensors go bad at the same time. Could this be an indication of an electrical or engine control module problem? Thanks.

Armando G Posted November 28, 2020 Report Share Posted November 28, 2020 Isn't it under warranty? Just have them look at it and do the work. I just got some warranty work done on my Ford...$4000, nothing out of my pocket. larryl, OhareFred and 2late4u 1 1 1 Quote Link to comment Share on other sites More sharing options...
John/Horace Posted November 30, 2020 Report Share Posted November 30, 2020 Look under hood at wiring harness close to cam shafts on top of engine for signs of chewed wiring. May have to remove the top plastic beauty cover to see properly. Lot of codes for a almost new car, wouldn’t be wear items yet. Any recent dead battery issues ? Often that generates some codes. Warranty no likely covering chewed wires. Hope that’s not it. Quote Link to comment Share on other sites More sharing options...
hexnut Posted November 30, 2020 Author Report Share Posted November 30, 2020 I did check out the connectors and wires yesterday. I made sure they were seated properly. Everything looked good. No battery issues since I have owned the vehicle. No codes since the original post. I cleared them again to see if I could narrow down the sequence. I am finding it hard to believe that both sides are throwing codes. Not sure if the warranty covers anything like sensors or wiring. Thanks.

John/Horace Posted December 2, 2020 Report Share Posted December 2, 2020 Bad fuel can create various engine issues...both sides. You may have cleared most of the fuel now so it’s ok, try filling up with super for a tank. Or add a decent fuel injector cleaner to the gas tank. The winter gas with the extra ethanol is probably at the stations now; has your fuel economy recently dropped badly? Ethanol does that but shouldn’t cause codes.

agm2112 Posted December 2, 2020 Report Share Posted December 2, 2020 Using a scanner (I´m using AlphaOBD on my phone) you can check all VVT actuators, perform VVT system test and clean all the camshaft phasers. I did it on my journey just for testing purposes. It makes many clicks on the camshaft, the engine accelerates, then almost stalls, and hopefully it gets rid of any sludge interfering on it. I believe this is a good starting point ! Quote Link to comment Share on other sites More sharing options...
Armando G Posted February 13, 2023 Report Share Posted February 13, 2023 @hexnut what was the result of this issue? I just got the same exact codes and am wondering if it is the sensors or a weak battery. i still have the original battery in the DJ and there have been a couple other electrical hiccups.

Jacmoose Posted March 20 Report Share Posted March 20 I have been fighting the same codes for 2 years now. I had both camshaft position sensors replaced with OEM parts and it fixed the problem for about 3000 miles, but it came back with vengeance to where it's very hard to drive. i used to able to clear the code and get a few hundred miles out of it before the engine light would come back on, now it comes back on immediately.
