Restore Peak Performance to Your GM Vehicle
Is your 2001 Chevrolet Monte Carlo, Impala, or other compatible GM vehicle suffering from perplexing engine issues? An erratic check engine light, poor fuel economy, stalling, or a no-start condition can often be traced back to a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, the PCM is critical for optimal performance, emissions, and drivability. This replacement PCM, part number 09378702, is the definitive solution to restore your vehicle’s factory operation and reliability.

Replacing a PCM used to mean a costly trip to the dealership for installation and programming. We’ve eliminated that hassle. When you purchase this module, we flash it with the latest official GM software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) during checkout. This ensures that when the part arrives, it’s a true plug-and-play component, calibrated for your car’s specific engine, transmission, and options. You get a fully functional brain for your car, ready for installation right out of the box.
From the Diagnostic Bay
We had a 2001 Impala come in with a ghost of a problem. The customer complained of random stalling at stoplights, but it would always restart immediately. There were no consistent trouble codes, just a history of random misfires. We checked fuel pressure, spark, and sensors—everything looked fine. After days of chasing our tails, we decided to monitor the PCM’s live data on a long drive. We finally saw it: for a split second, the PCM would command the fuel injectors to shut off for no reason. It was a classic case of an internal PCM fault that was too intermittent to set a hard code. Swapping in a pre-programmed module like this one solved the problem instantly. It’s a reminder that sometimes the most confusing issues lead back to the vehicle’s central computer.

Frequently Asked Questions
Do I need to get this PCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready to be installed with the latest GM software for your specific car.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. It tells us everything about your vehicle’s factory build, including the engine, transmission, and other options. We use this to load the precise software your car needs to run correctly.
Where is the PCM located on a 2001 Monte Carlo?
On the 2001 Monte Carlo, as well as the Impala, Intrigue, Aurora, and Silhouette, the PCM is typically located in the engine compartment on the driver’s side (LH), often integrated with the air filter housing. On the Grand Am, it’s found in the LH center dash area.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of your original PCM, then yes, this replacement part will resolve the issue. However, if the light is caused by a faulty sensor or another component, that part will still need to be addressed.
Is any special procedure required after installation?
In many cases, a security relearn procedure (also known as a Passlock or anti-theft relearn) is required after installation. This procedure is simple, does not require special tools, and involves a sequence of key turns. Instructions are readily available online or in service manuals. A Crankshaft Variation (CASE) relearn may also be needed for optimal performance, which requires a capable scan tool.
