2002 Dodge Intrepid P0352 Code: Diagnosis and Fix Guide

Model: Dodge Intrepid Fault Code: P0352 Posted: 2014-05-12 19:01

I'm currently experiencing a P0352 diagnostic trouble code on my 2002 Dodge Intrepid. The onboard diagnostics system is showing this specific fault, but no other related codes are present. I've performed several tests including voltage checks, resistance measurements, and compression testing (all cylinders show 150 psi). I also replaced the oxygen sensor on bank #2 and the spark plug and coil assembly. After following troubleshooting steps recommended by Auto Joe, I ordered a rebuilt Engine Control Module (ECM) from All Computers. Once installed, the P0352 code disappeared entirely. This suggests that the ECM was the root cause of the issue.

The term 'car onboard diagnostic' might refer to key cycling (on-off cycles). If this is the case, such actions only provide limited diagnostics and won't resolve underlying issues. A proper scan tool is required for accurate readings.

Hi Auto Joe, Kev2, and Mohawkmter — thank you all for your guidance. After following the diagnostic steps outlined by Auto Joe, I determined that the Engine Control Module (ECM) was faulty. I replaced it with a rebuilt unit from All Computers, and the P0352 code has fully disappeared. I also replaced the O2 sensor on bank #2, which previously triggered a fault before this issue began — that code is now resolved as well. I performed a no-id test on all injectors and confirmed 150 psi compression across all cylinders. All resistance and voltage tests recommended by Auto Joe were completed successfully. I'm truly grateful for your help.

Thanks for sharing the resolution. It appears the issue was related to a failing sensor or signal at higher RPMs. A lab scope would have quickly identified this problem. PCM replacements can be expensive on some vehicles, especially with flashing issues. Online diagnostic tools are often more affordable than dealer services.

You're welcome! I paid $170 for the rebuilt ECM — about $20 more than a standard one-hour service at my local shop. While it was costly, I believe it was worth the investment because of the knowledge I gained from your guidance. Thank you so much, Mezzbike.

Please don't assume automotive technicians are overcharging — consider a medical visit: a $150 office visit might result in a prescription to fill elsewhere and another appointment weeks later. The same applies to vehicle diagnostics; proper testing should be accessible and fair.

Kev2, I didn't suggest anything negative — my car has been to the shop multiple times since purchase, with over $2000 in repairs. I couldn’t afford another full restoration. I asked my mechanic about diagnostic costs and decided to try a DIY approach using your advice. That decision was made out of necessity, and I’m truly thankful for the support. I didn’t mean to offend anyone.

I fully agree with the DIY mindset — we're all here to help. However, it's becoming increasingly difficult to perform accurate diagnostics without access to a vehicle-specific PCM interface or scanner tools.
