What is the pcm on a Pontiac grand prix gtp?

The Pontiac Grand Prix GTP uses a Powertrain Control Module (PCM), sometimes also referred to as an Engine Control Module (ECM). There isn't one specific part number that covers all years of the GTP. The PCM's part number varies depending on the year and specific engine options.

To find the correct PCM for *your* specific Grand Prix GTP, you'll need to provide the year of manufacture. Then, you can:

* Check the PCM itself: The part number is usually stamped on the module itself. You'll likely need to remove some covers or shrouds to see it clearly.

* Use an online parts database: Websites like AutoZone, Advance Auto Parts, or RockAuto allow you to search for parts by vehicle year, make, and model. Entering your GTP's details will show the correct PCM.

* Consult a repair manual: A repair manual specific to your year's Grand Prix GTP will list the PCM part number.

Without the year of your Pontiac Grand Prix GTP, I cannot give you a specific PCM part number.
