Is Your Grand Am Running Rough? The PCM Might Be the Culprit.
If your 2000-2001 Pontiac Grand Am is suffering from mysterious check engine lights, erratic shifting, poor fuel economy, or even a no-start condition, the problem often points to a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM manages everything from fuel injection and ignition timing to transmission shift points. When it begins to fail, it can cause a cascade of frustrating and hard-to-diagnose issues. This isn’t just an inconvenience; it’s a critical component failure that affects your vehicle’s performance, safety, and emissions.
From the Diagnostic Bay
We had a 2001 Alero with the 2.4L engine come into the shop that was giving the owner fits. The transmission would shift hard from first to second, but only when warm. No transmission codes were present, just a generic P0601 internal memory error from the PCM. After checking all the wiring and grounds, we suspected the engine computer itself was the issue. We installed one of our VIN-programmed PCMs, and the difference was immediate. The hard shifting vanished, and the car drove like new. It’s a classic example of how a faulty PCM can manifest as a transmission problem, fooling even experienced mechanics.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with communication or internal module error codes.
- ✔ Poor engine performance, including misfires, hesitation, or stalling.
- ✔ Decreased fuel efficiency for no apparent reason.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ The engine cranks but refuses to start.
- ✔ Failure to pass state emissions testing.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your car’s main computer. It controls the engine and transmission functions, managing fuel delivery, spark timing, emissions systems, and automatic gear shifts to ensure optimal performance and efficiency.
Is this module ready to install when I receive it?
Yes! This PCM is fully programmed to the VIN you provide during checkout. This makes it a plug-and-play installation. In most cases, no further programming is required. We always recommend disconnecting the battery before swapping modules.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your insurance/registration documents.
What if my original part number is different?
This module is a direct replacement for several part numbers, including 09356249, 16268310, 9356249, and 9392873. As long as your vehicle is listed in our fitment chart and your original part number is one of these, this module will work correctly once programmed to your VIN.
Will this PCM require a security relearn procedure?
For many GM vehicles of this era, a simple security relearn procedure may be necessary after installation. This can typically be done without special tools by cycling the ignition key and takes about 30 minutes. Instructions are widely available online for the GM Passlock system.
