Tired of That Stubborn Check Engine Light?
Are you dealing with frustrating and unpredictable issues in your Grand Prix, Impala, or Monte Carlo? An engine that stalls for no reason, harsh or erratic shifting, or a check engine light that just won’t go away can point directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it affects your vehicle’s performance, fuel economy, and reliability. This pre-programmed Engine Control Module is the definitive, hassle-free solution to get your trusted GM vehicle running like it should again.

- Intermittent or random engine stalling
- Unexplained Check Engine Light (CEL) with various codes
- Communication errors with diagnostic scan tools
- Poor fuel economy and reduced engine power
- Harsh or delayed automatic transmission shifting

Expert Insight from the Shop Floor
We see it all the time: a customer comes in with a 2002 Impala that has a persistent camshaft sensor code. They’ve replaced the sensor twice, checked the wiring, and are at their wit’s end. The car sometimes stalls at red lights. The real culprit isn’t the sensor; it’s a failing driver circuit inside the original PCM. The computer can no longer properly read the signal from a perfectly good sensor. Installing a correctly programmed 12209624 PCM doesn’t just clear the code—it fixes the root cause, restoring smooth operation and giving the owner their reliable daily driver back.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the essential programming. The module is flashed to your vehicle’s VIN before it ships. For most of these GM vehicles, you will only need to perform a simple security relearn procedure, which can be done in your driveway without any special tools.
Where do I provide my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. To ensure a smooth process, please double-check it for accuracy before sending.
What is the security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows the components to recognize each other.
How do I know if my PCM is really the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified mechanic is always the best course of action. A faulty 12209624 PCM often causes problems that seem unrelated, making it one of the last components people check.
Is this compatible with my car?
This module fits a wide range of GM vehicles from 2001-2003 with the 3.8L engine. Please review the detailed fitment list on this page and confirm that your original module’s part number is 12209624 or 12210234 to ensure compatibility.
