My check engine light is on

yes. I was told it had the same warranty, and it is a 9 year old car, after all. Do you not think that's a good idea? My other alternative is to return to the dealer for a new PCM at twice the cost.

Wait, isn't the PCM part of the emissions control system? Any part of that system is under warranty, for 80,000 miles, by federal law.

the emissions warranty is 8 yr or 80K whichever comes first, and only for these components:

What Are Specified Major Emission Control Components?

There are three specified major emission control components,
covered for the first 8 years or 80,000 miles of vehicle use on 1995
and newer vehicles:

* Catalytic converters.

* The electronic emissions control unit or computer (ECU).

* The onboard emissions diagnostic device or computer (OBD).

I just never heard of a re-manufactured computer before.

Guess that would be pulled out of a junk car and washed off.

I thought the Powertrain Control Unit (PCU), Powertrain Control Module (PCM) Electronic Control Unit (ECU) and Electronic Control Module (ECM) are different names for the same critter.
