Restore Peak Performance to Your GM Vehicle
Is a persistent Check Engine Light and erratic engine behavior turning your reliable family vehicle into a source of daily stress? Unexplained stalling, poor fuel economy, and rough shifting can point directly to a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the central command for your engine’s performance and efficiency. We provide a dependable, pre-programmed solution to get your car running smoothly and safely again, restoring the reliability you count on.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous frustrating ways. If you’re experiencing any of the following, this module is the definitive solution:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) related to the module, such as P0601, P0602, P0605, or P0606
- Unexplained engine stalling or hesitation
- Rough or inconsistent idling
- Poor acceleration and loss of power
- Decreased fuel mileage
- Failure to pass emissions testing
- Harsh or erratic transmission shifting
This professionally programmed unit for your 2001-2002 Pontiac Montana PCM directly addresses these issues by restoring the critical link between your vehicle’s sensors and its mechanical systems, ensuring everything operates in perfect harmony as the factory intended.

An Expert’s Note on VIN Programming
For these early 2000s GM vehicles, VIN programming is not just a convenience—it’s critical. The PCM communicates with the Body Control Module (BCM) and the anti-theft system (VATS/Passlock). A generic, non-programmed module will often result in a no-start condition because the security systems won’t recognize it. Our VIN-specific flashing ensures all components communicate correctly from the moment you turn the key, saving you from a frustrating and costly trip to a dealership for additional programming.
Frequently Asked Questions
Do I need to do any extra programming myself?
No. This PCM arrives fully programmed to your vehicle’s VIN and is ready for installation. In some cases, a simple security relearn procedure may be required, which can be done without any special tools and takes about 30 minutes. We include instructions for this process.
Where is the PCM located on my vehicle?
On most compatible models like the Pontiac Montana, Chevy Venture, and Buick Rendezvous, the PCM is located in the engine compartment on the driver’s side, typically inside the air filter box assembly for protection.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Will this fix my specific check engine light codes?
This module is a guaranteed fix for internal module failure codes (like P0601-P0606). If your codes are for specific sensors (like an oxygen sensor or MAP sensor), you should diagnose and replace those parts first. A faulty PCM can sometimes cause false sensor codes, but it’s always best practice to rule out other components.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to a computer that only controls engine functions. A PCM (Powertrain Control Module) is more integrated and controls both the engine and the transmission. This part is a PCM.
