Is Your Vehicle Running Rough or Not Starting at All?
If your 2000-2001 Oldsmobile Alero, Pontiac Grand Am, or Chevrolet Cavalier is experiencing perplexing issues like stalling, erratic engine behavior, poor fuel economy, or a complete no-start condition, the culprit is often a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing the engine, transmission, and dozens of other critical systems. When it fails, it can cause a cascade of problems that are frustrating and difficult to diagnose. This genuine, used OEM PCM, part number 09356249, is the reliable and cost-effective solution to get your vehicle back on the road and running as it should.
From the Diagnostic Bay
A customer brought in a 2001 Pontiac Grand Am 2.4L that would crank but never start. They had already replaced the spark plugs, ignition coils, and even the fuel pump, but nothing worked. The check engine light was on, but their basic code reader couldn’t communicate with the computer. That was our first clue. We hooked up our professional scan tool and found the same thing: no communication with the PCM. After verifying the PCM was receiving proper power and ground, we knew the internal circuitry had failed. We sourced a quality used module, programmed it to the car’s VIN, performed the security relearn, and it fired right up on the first try. A faulty computer can mimic many other part failures, making it a tricky diagnosis without the right approach.
Symptoms of a Failing Powertrain Control Module
- ✔ Check Engine Light is illuminated with communication error codes.
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Misfire codes (like P0300) that don’t resolve after replacing ignition components.
- ✔ Failure to pass an emissions test.
The Right Solution: A Pre-Programmed 2000-2001 Alero PCM
Replacing the PCM isn’t as simple as swapping a part. A new or used module must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software updates to function correctly. Our service eliminates the need for an expensive trip to the dealership. When you purchase this module, you provide us with your VIN, and our technicians will flash the computer specifically for your car. This ensures that it communicates perfectly with all the other modules and sensors in your vehicle, restoring original performance and functionality.
This unit is a direct replacement for several part numbers, including 09356249, 16268310, and 9392873. It is meticulously inspected and sourced from a salvaged vehicle, providing you with a genuine OEM part at a fraction of the cost of a new one. Don’t settle for questionable aftermarket electronics; trust the component that your vehicle was built with.
Installation and Security Relearn
Physical installation is straightforward. On most of these models, the PCM is located in the engine bay or under the dash. However, after installation, a Security Relearn Procedure (also known as a Passlock or VATS relearn) is required. This procedure syncs the new PCM with your vehicle’s anti-theft system. It’s a simple process that you can do yourself in about 30 minutes with just the ignition key and does not require any special tools. We include instructions to guide you through this essential final step.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is essential for programming the PCM. It contains specific information about your car’s engine, transmission, and factory options. Programming with the VIN ensures the computer has the correct software and calibration files to operate your vehicle properly.
Is this a plug-and-play part?
Almost. The module comes pre-programmed to your VIN, making the software side ready to go. However, you will need to perform a security relearn procedure after installation to sync the module with your car’s anti-theft system. Instructions are provided.
Where is the PCM located on my vehicle?
On the Cavalier and Sunfire, it’s typically on the right-hand (passenger) side of the engine compartment. On the Alero and Grand Am, it’s often found under the dash on the left-hand (driver) side. Always disconnect the battery before removal or installation.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM or internal processor error codes, then yes, this part will resolve the issue. However, if the light is on due to other failing sensors or components, those issues will still need to be addressed.
Is this a used part?
Yes, this is a genuine OEM computer sourced from a salvaged vehicle. Each unit is inspected to ensure it is a functional and reliable component, offering OEM quality without the new-part price tag.
