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!

Are you able to post the exact engine error code numbers that are set. If not then go to a place like Auto Zone and have a scan done. The scan will show any codes that are set and the scan at Auto Zone is free.

Did you have the new PCM programmed?
You may find out the dealer was the cheapest route.

Racer is right. Knowing the code number is half the battle.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Check all your fuses.... A blown O2 heater fuse can cause some confusion sometimes......
Cycling the key from off to the on position 3 times should bring up the codes in the odometer.....You have to time it just right......

The ignition-key fault code is 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.

That is a "high voltage" code for the 0/2. That code is rarely caused by the sensor itself. It's usually something else getting into the circuit.
