Is Your GM Vehicle Acting Up? It Could Be The Powertrain Control Module.
If you’re experiencing frustrating engine problems with your 2000-2002 Pontiac Sunfire, Chevrolet Cavalier, or other compatible GM model, a faulty Powertrain Control Module (PCM) is a likely culprit. The 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 fails, it can cause a cascade of issues that can be difficult to diagnose and leave your car unreliable or even undrivable. This replacement module, part number 9392873, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We once had a 2001 Cavalier come into the shop with a persistent check engine light and a rough idle that three other mechanics couldn’t solve. The owner had already spent a small fortune replacing the spark plugs, ignition coils, and even the mass airflow sensor. After hooking up our professional scan tool, we noticed erratic data readings from multiple sensors that didn’t make sense. Instead of chasing ghosts and replacing more parts, we focused on the source: the PCM. A quick swap with a correctly programmed module like this one, followed by a security relearn, and the car ran like new. It’s a classic case of treating the disease, not just the symptoms.
Common Symptoms of a Failing PCM
A failing engine computer can manifest in various ways. If you notice any of the following signs, it’s time to consider a replacement. Look out for:
- ✔ Check Engine Light: An illuminated or flashing Check Engine Light is the most common indicator. You may see codes related to sensor circuits, module communication errors, or random misfires.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire, especially under load.
- ✔ No-Start Condition: Your vehicle may crank but refuse to start because the PCM isn’t properly controlling the fuel or spark.
- ✔ Poor Fuel Economy: Incorrect signals from the PCM can lead to an inefficient air-fuel mixture, causing your vehicle to consume more gasoline than usual.
- ✔ Failed Emissions Test: A malfunctioning PCM can prevent the emissions systems from operating correctly, leading to an automatic failure at the testing station.
- ✔ Harsh or Erratic Shifting: The PCM also controls the transmission, and a faulty unit can cause jerky shifts, delayed engagement, or being stuck in one gear.
A Plug-and-Play Solution for Your 2000-2002 Sunfire PCM
Don’t let a bad computer keep you off the road. This is a genuine, used OEM Powertrain Control Module that has been thoroughly tested for full functionality. The best part? We take the guesswork and expense out of the equation by programming it specifically for your vehicle before it ever leaves our facility. Simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN) during checkout, and our technicians will flash the module with the latest, most up-to-date software from General Motors. This ensures perfect compatibility and function, just like the original unit.
This module is a direct replacement for several part numbers, including 09356249, 16268310, and 9392873. It is designed to fit the following vehicles:
- Pontiac Sunfire: 2000, 2001, 2002 (with ID 9356249)
- Chevrolet Cavalier: 2000, 2001, 2002 (with ID 9356249)
- Pontiac Grand Am: 2000, 2001 (with 2.4L engine)
- Oldsmobile Alero: 2000, 2001 (with 2.4L engine)
After installation, a simple security relearn procedure (often called a ‘key-cycle relearn’) is required to sync the new module with your vehicle’s anti-theft system. This can typically be done in your own driveway without any special tools, and we can provide instructions to guide you through the process.
Frequently Asked Questions
Do I need to have this PCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation and a simple security relearn procedure.
Is this a new part?
This is a high-quality, tested, and fully functional used OEM part sourced from a salvaged vehicle. This provides OEM reliability at a fraction of the cost of a new unit.
What is the security relearn procedure?
It’s a simple process to sync the new PCM with your car’s anti-theft system. It usually involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’, and repeating this cycle three times. This allows the components to recognize each other.
Where do I find my VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
How do I know if this part will fit my car?
Please check the compatibility list provided. This module fits 2000-2002 Sunfire & Cavalier, and 2000-2001 Grand Am & Alero with the 2.4L engine. Matching your original part number to 9392873, 09356249, or 16268310 will also confirm fitment.
