Restore Peak Performance to Your Pontiac Montana
Is your 2001-2002 Pontiac Montana suffering from mysterious engine problems? Issues like a persistent check engine light, rough idling, stalling, or poor fuel economy often point to a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it falters, the entire performance and reliability of your vehicle are compromised. This replacement PCM, part number 09360210, is the definitive solution to restore your vehicle’s factory performance and dependability.
From the Diagnostic Bay
We once had a 2002 Grand Am (which uses this same PCM) come into the shop with a persistent P0171 lean code. The owner had already replaced the MAF sensor, both oxygen sensors, and the fuel filter, but the check engine light always returned. After confirming fuel pressure and checking for vacuum leaks, we hooked up our diagnostic scanner. We noticed the short-term fuel trim data was erratic and unresponsive. A deeper dive revealed the PCM’s internal driver for the fuel injectors was failing, leading to an incorrect fuel mixture. A new, properly programmed PCM fixed the issue instantly. This is a classic case where chasing sensors costs more time and money than addressing the root cause: the vehicle’s computer.
Common Symptoms of a Failing PCM
If you’re experiencing any of the following issues, a faulty engine computer could be the culprit. A failing module can manifest in various ways, making diagnosis tricky. Look out for these common warning signs:
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Unexplained engine stalling or cutting out while driving.
- ✔ Difficulty starting the engine or a no-start condition.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or erratic engine idling.
- ✔ Harsh or delayed automatic transmission shifting.
- ✔ Failure to pass state emissions inspections.
- ✔ Communication errors with diagnostic scan tools.
The Ideal Solution: A Programmed 2001-2002 Montana PCM
Don’t let a faulty computer keep your vehicle off the road. This replacement module is the most reliable and straightforward solution available. We take the guesswork and hassle out of the repair process. Before this unit ships, we flash it with the latest GM-certified software updates specific to your vehicle’s unique Vehicle Identification Number (VIN). This ensures that the module is perfectly calibrated for your engine, transmission, and factory options. The result is a plug-and-play installation that restores the precise control your vehicle had when it left the factory.
Simple Process, Lasting Results
Our goal is to make your repair as simple as possible. Here’s how it works:

- Provide Your VIN: After your purchase, simply send us your 17-digit VIN. This is critical for the programming service.
- We Program & Ship: Our technicians will program the module with the correct software and ship it directly to you, ready for installation.
Installation is typically straightforward. The PCM is located in the LH engine compartment on the Montana. Always disconnect the negative battery terminal before swapping modules to prevent electrical damage. Once installed, your vehicle may require a security or CASE (Crankshaft Angle Sensor Error) relearn procedure, which can be performed by most automotive shops or with a high-level diagnostic scan tool.
Broad GM Compatibility
While this is a perfect fit for the 2001-2002 Pontiac Montana, this versatile PCM is also the correct service part for a wide range of other GM vehicles from the same era. It is a direct replacement for part numbers 12209614, 12202600, and 09360210. It fits models such as the Oldsmobile Alero and Silhouette, Chevrolet Impala and Monte Carlo, Buick Century and Regal, and Pontiac Grand Am and Aztek, among others.
