Restore Peak Performance to Your GM 3.8L V6
Is your Pontiac Firebird, Chevrolet Camaro, or other GM vehicle with the legendary 3.8L V6 engine running poorly? Experiencing issues like a persistent check engine light, stalling, rough idling, or erratic transmission shifting? The Powertrain Control Module (PCM), often called the engine computer, is the central command center for your entire powertrain. When it begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose problems. This genuine GM PCM, part number 12209624 (also compatible with 12210234), is the definitive solution to restore your vehicle’s reliability and performance.
Your Solution: A Pre-Programmed 2001-2002 Firebird PCM
Don’t settle for a generic, unprogrammed module that will require an expensive trip to the dealership. We take the guesswork and hassle out of the repair. This unit is professionally flashed with the latest GM-certified software updates specifically for your vehicle. By providing us with your Vehicle Identification Number (VIN) during checkout, we ensure the module arrives at your door ready for a straightforward installation. This programming is critical for proper communication with your vehicle’s other modules, including the anti-theft system (VATS/Passkey), transmission, and instrument cluster.
From the Diagnostic Bay
We had a 2002 Chevy Impala with the 3.8L come in with a classic intermittent stalling complaint. The customer said it only happened after driving for 30+ minutes on a hot day. We scanned it and found no hard codes, just a history of lost communication faults. After checking all the wiring and grounds, we suspected the PCM. On a long test drive with a scanner attached, we saw the data stream for the crank sensor start to go haywire right before it stalled. It was a textbook case of a PCM failing under heat soak. We replaced it with a pre-programmed 12209624 module, and the car has been running perfectly ever since. These symptoms are very common for this specific module across the entire GM 3.8L platform.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light: The most common indicator, often with communication-related trouble codes (U-codes) or performance codes.
- ✔ No-Start or Hard-Start: The engine may crank but fail to start, or take an excessively long time to fire up.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy.
- ✔ Rough Idling or Stalling: The engine may stall unexpectedly at stops or idle erratically.
- ✔ Erratic Transmission Shifting: The PCM controls shift points, and a faulty module can cause harsh or delayed shifts.
- ✔ Failed Emissions Test: An improperly functioning PCM cannot correctly manage the engine’s emissions systems.

Frequently Asked Questions
Do I need to program this PCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s 17-digit VIN when you place your order, and the module will arrive ready for installation. This ensures it works correctly with your engine, transmission, and security system.
What is the difference between a PCM and an ECM?
The terms are often used interchangeably. ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. A PCM is a more advanced type of ECM that also controls the transmission and other powertrain functions. For these GM vehicles, PCM is the correct term.
Where is the PCM located on my 2002 Firebird?
On the 2001-2002 Firebird and Camaro, the PCM is located in the engine compartment, typically behind the passenger-side (RH) strut tower. On front-wheel-drive models like the Impala, Grand Prix, and LeSabre, it is usually found in the engine bay on the driver’s side (LH), often attached to the air filter box assembly.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. However, the check engine light can be triggered by hundreds of different problems. It is always recommended to have your vehicle properly diagnosed with a code scanner to confirm the PCM is the root cause of the problem before ordering.
Is this a direct replacement for part number 12210234?
Yes, GM service part numbers 12209624 and 12210234 are interchangeable. This module is a correct replacement for either of those original part numbers.
