WJ 2.7 CRD P0201, P0202, P0203, P0204, P0205 Issue I seem to have resolved this issue but thought I'd add a thread for the benefit of others. FWIW, this is related to my need a battery thread.
The story is I was driving down the shops, the engine started to misfire just a tad then it completely stalled. Tried to start it and it would fire but not run. Then the battery died so I suspected I had a low voltage issue and the computer was complaining. With a newish battery it ran a bit longer (however with the MIL light on) then crapped itself if I put it in gear or pressed the brake pedal. Got it home, check for codes and I saw a P0203 which can indicate a bad injector, bad wiring or a faulty ECU. I ended up running through the diagnostic procedure and found there was an issue for the majority of procedures. Here is the offending text: Quote:
Anyway all of the checks were fine, all resistances and voltages were on the money so the ECU and wiring looked good. I reconnected all injector and ECU connectors and tried again and all was good, car started and ran fine. Time will tell but it looks like I had a dirty connector on injector 3 which created the issue, the quick re-seat appears to have solved the problem. If it doesn't clear itself I may have a faulty injector or ECU, I hope this isn't the case. For info these are the manuals fault conditions in this case for Inject 1: Quote:
