CHRYSLER TOWN AND COUNTRY MECHANIC PROBLEM

2005 Chrysler Town and Country • 190,000 miles

2005 Chrysler Town and Country Van LX, 3.3 liter engine, 190k miles

Check Engine Light (CEL) was on, failed emissions test in Tennessee, O2 sensor showed as the problem.

My mechanic (not the dealership) replaced the O2 sensor. The CEL came on immediately afterward. My mechanic traced the problem to the only thing they could figure which was a bad Engine Control Module/Powertrain Control Module (ECM/PCM) (two different names for the same thing, I think).

I ordered a rebuilt ECM from a reputable company on eBay. My mechanic installed it and the CEL again came on immediately afterward. My mechanic is stumped. I wonder if my original ECM was even bad.

The dealership charges over $90 just to check the ECM and can only check the one that is on the vehicle; not the one that was replaced. The eBay company has a tech support line, and I left three messages on Friday afternoon. I haven't received a response yet.

What else could this be? Thanks in advance!

What was the code?

Put back the original pcm and get a new mechanic.

Pay the 90 bucks and get it checked out correctly. Guesses never work and you spent more than the 90 now

The ignition-key method brought up a fault code of P0132. That's the only one that came up. I won't be able to find out for sure which sensor has been replaced until the shop opens on Monday, but it probably was the O2 Sensor 1.
