Is the 2000-2001 pcm for dodge caravan compatible with 2002 pcm?

No, a 2000-2001 PCM for a Dodge Caravan is generally not compatible with a 2002 PCM. While they might seem similar, there are likely significant differences in the software and hardware between model years. Even minor changes in the vehicle's systems (sensors, emissions controls, etc.) can render a PCM incompatible.

Using an incorrect PCM can lead to a variety of problems, including:

* Non-starting vehicle: The engine may not even crank.

* Check engine light: Numerous codes will likely illuminate.

* Erratic performance: The vehicle might run poorly, even if it starts.

* Damage to other components: The wrong PCM could potentially damage other parts of the vehicle's electrical system.

Always use a PCM specifically programmed for the year, make, and model of your vehicle. It's best to get a PCM with the correct part number from a reputable parts supplier.
