Is Your Pontiac Sunfire or Chevy Cavalier Giving You Headaches?
If you’re dealing with a persistent check engine light, erratic engine behavior, a no-start condition, or false sensor codes, the root cause is often a failing Powertrain Control Module (PCM). Over my 20+ years in the shop, I’ve seen countless GM vehicles from this era, like the Sunfire, Cavalier, Grand Am, and Alero, come in with these exact issues. The PCM is the brain of your engine, and when it starts to fail, it can create a diagnostic nightmare, leading to wasted time and money on parts you don’t need.

From the Shop Floor: “A customer’s 2001 Sunfire came in last week with a no-start condition. They had already replaced the fuel pump and crankshaft position sensor based on a friend’s advice, with no luck. After a quick scan, I saw no communication with the PCM. Instead of just swapping the part, we first checked the power and ground pins at the PCM connector—they were perfect. That confirmed the internal failure. We installed one of our VIN-programmed modules, and the car fired right up. It’s a classic case where diagnosing the brain first saves hundreds in unnecessary parts.”

Plug-and-Play Installation: No Dealer Visit Required
Installing your replacement module is a straightforward job you can do at home. Just follow these steps carefully.
- Safety First: Disconnect the negative terminal from your car’s battery and wait 10 minutes for the system to fully discharge.
- Locate the PCM: On most Sunfire and Cavalier models, it’s in the engine compartment on the passenger side, often near the air filter box. For Grand Am and Alero models, it’s typically under the dash on the driver’s side. Refer to your vehicle’s fitment location above.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old PCM. Inspect the pins on the harness side for any corrosion or damage. Clean them with a dedicated electronics cleaner if necessary.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt your new, pre-programmed PCM into place.
- Reconnect and Finalize: Securely plug the wiring harnesses into the new module. You should hear a ‘click’ as they lock. Reconnect the negative battery terminal. The vehicle is now ready to start.
After purchase, simply send us a message with your 17-digit VIN, and we’ll handle the programming. Get your car back on the road quickly and confidently with a reliable, ready-to-install 2000-2002 Sunfire PCM.
