Is Your GM Vehicle Running Rough?
Is your Chevrolet Impala, Monte Carlo, or another GM vehicle from the early 2000s acting up? Stalling at traffic lights, shifting erratically, poor fuel mileage, or a persistent check engine light can be incredibly frustrating.

Expert Insight: The Critical Importance of VIN Programming
From over 20 years in diagnostics, I’ve seen countless drivers replace a PCM only to find the car still won’t start. That’s because the module needs to communicate with your vehicle’s security system (GM’s Passlock/VATS). Without proper programming, the security system sees the new PCM as a threat and prevents the engine from starting. We handle this critical programming before we ship, using your VIN to ensure the module is a perfect electronic match for your specific car. This pre-programming is the key to a successful, hassle-free DIY repair and is a service that sets our modules apart.
By providing us with your VIN upon purchase, you ensure that the 2001-2002 Impala PCM 09378702 you receive is perfectly matched to your vehicle’s factory settings. This critical step guarantees a seamless installation and restores the precise functionality your car had when it left the factory.
Frequently Asked Questions
Do I need to have this programmed by a dealer or mechanic?
No. We handle all the programming for you before the part is shipped. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to be installed and started.
What information do you need from me?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this part difficult to install?
For most of the compatible vehicles, the PCM is located in the engine compartment, often within the air filter box assembly. Installation typically involves disconnecting the battery, removing the air filter housing, unplugging the electrical connectors from the old module, and swapping in the new one. It is a manageable job for a confident DIYer with basic hand tools.
Will this fix my check engine light?
This module will resolve any check engine light and diagnostic trouble codes (DTCs) that are directly caused by a failing PCM, such as internal processor errors (P0601) or communication faults. If your check engine light is on for another reason (e.g., a bad oxygen sensor), that issue will need to be addressed separately.
How do I know for sure that my old PCM is bad?
While a professional diagnosis is always best, common signs of PCM failure include multiple unrelated trouble codes, intermittent stalling that can’t be traced to other components, harsh shifting, and a no-start condition where the engine cranks but won’t fire. If you’ve already checked your fuel and ignition systems, the PCM is a strong possibility.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty. This gives you assurance and protects your investment in getting your vehicle back in top condition.
