Gonna try and not make this a rant session, as frustrated as I am. Moreso hoping to hear from others who have had this code and what worked for them.
My trouble started with traction control light coming on and keep going into limp mode. Several codes were thrown and I decided to take her to the dealer thinking maybe I screwed something up when I replaced rocker arms on the passenger side of the vehicle. I also had ticking on the driver side and figured let them go in and repair the drivers side and get this thing finished. They replaced two cam shafts and rocker arms and all was great.
Few days later I get the error code. Long story short, I replaced the camshaft position sensor myself with an aftermarket and suspected maybe that was the issue. Dealer threw in a molar one and said the aftermarkets are hit or miss. Great. Sensor in and no code for about a month. Code came back yesterday. I’ve already thrown a lot of money at this thing and can’t do it anymore. I’ve done a lot of research and seems the P0303 is a rabbit hole of possible causes.
Whats confusing is that other than the check engine going on, there’s no issue with the engine or acceleration etc etc. She’s running great. I cleared the code yesterday and it’s back today. Also it seems to only trip the check engine light when I’m parked with the engine running. Not sure if that’s important to the troubleshooting.
I’m just at the end of my patience and financial ability to try and fix this thing. I’ve always taken care of this jeep. Oil changes at 4K miles and all maintenance. I don’t beat on it. It’s running great except for this code not going away. Maybe it’s a bad fuel injector? But there’s no engine issues that would lead me to believe that’s the case.
I did a tuneup last summer and the clip for the coil pack for cylinder three snapped off. The connection still seats nicely but I’m wondering if that could be a cause? At this point I’m at a loss. Dealer said could be electrical but I don’t have the money to have them diagnose and go in a wild good chase. If anyone has gone through this nightmare and can share any advice that I could do myself I would appreciate it. Really don’t want to let her go but I may have to. It’s a 2014 with 129k and very well maintained.
