Is Your Vehicle Experiencing Critical Performance Issues?
The Powertrain Control Module, or PCM, is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can cause a wide range of frustrating and difficult-to-diagnose problems. If your Buick, Chevrolet, Pontiac, or Isuzu is stalling, running rough, getting poor gas mileage, or has an illuminated Check Engine Light that won’t go away, a faulty PCM could be the root cause. This module is the direct-fit, reliable solution to restore your vehicle’s performance and drivability.
From the Diagnostic Bay
We had a ’98 Grand Am come in with a persistent random misfire (P0300 code). The owner had already replaced the spark plugs, wires, and even the coil packs with no success. After confirming fuel pressure and checking for vacuum leaks, we connected an oscilloscope to the injector and ignition control signals from the PCM. We discovered the signal for cylinder 2’s injector was dropping out intermittently. A new, correctly programmed PCM like this one solved the issue instantly. It’s a classic reminder that when all the mechanical components check out, the controller itself is often the culprit.
Common Symptoms of a Failing Powertrain Control Module
- ✔ Unexplained Check Engine Light that may show communication error codes.
- ✔ Vehicle fails to start or stalls unexpectedly while driving.
- ✔ A noticeable and sudden decrease in fuel efficiency.
- ✔ Rough idling, engine hesitation, or severe misfires.
- ✔ Harsh, erratic, or delayed automatic transmission shifting.
- ✔ Failure to pass state emissions inspections due to module-related faults.

Frequently Asked Questions
Do I need to have this module programmed?
No. This module comes fully programmed to your vehicle’s specific VIN before it is shipped. It is ready for installation upon arrival, saving you a trip to the dealership.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct software for your car’s specific configuration.
Will any additional procedures be required after installation?
In some cases, a security relearn procedure (often called a CASE relearn or Passlock relearn) may be necessary for the vehicle to start. This procedure pairs the new PCM with your vehicle’s anti-theft system and can typically be performed by the owner without any special tools.
How can I be sure this part fits my vehicle?
Please review the detailed fitment list on this product page. The most reliable method is to match the part number from your original module to one of the compatible service numbers listed: 16228016, 8162280160, or 16245305.
What is the difference between a PCM, ECM, and ECU?
These acronyms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate term for this part, as it controls both engine and transmission functions. ECM (Engine Control Module) or ECU (Engine Control Unit) typically refers to a computer that manages only the engine.
