Is Your Cavalier, Sunfire, or Grand Am Giving You Headaches?
There’s nothing more frustrating than a vehicle that won’t run right. If you’re dealing with a persistent Check Engine Light, poor fuel economy, stalling, a rough idle, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). This component is the electronic brain of your engine, and when it malfunctions, it can cause a wide range of confusing and difficult-to-diagnose issues. In my 20+ years as a technician, I’ve seen hundreds of these GM vehicles where a faulty PCM was the root cause of drivability problems that other shops couldn’t solve.
The Direct, No-Hassle Solution for Your GM Vehicle
Forget expensive dealership diagnostics and programming fees. This is a thoroughly tested, genuine used GM PCM that is professionally programmed specifically for your car. Before we ship it, we flash the module with the latest GM-released software updates using the Vehicle Identification Number (VIN) you provide. This critical step ensures that the computer is a perfect match for your vehicle’s specific configuration, resolving software bugs and improving performance from the moment you install it. This isn’t just a replacement part; it’s a complete, ready-to-install solution.
Expert Pro Tip: Before you replace your PCM, take a moment to inspect the main ground connections. On many of these Cavalier and Sunfire models, the primary engine-to-chassis ground strap is located on a transmission bell housing bolt. Over the years, this connection can corrode, causing high resistance. This poor ground can mimic a wide array of PCM failure symptoms, including communication errors and erratic sensor readings. A quick cleaning with a wire brush can sometimes solve the problem and is a vital check before installing your new part.

Simple Installation: Get Back on the Road Fast
Installing your new PCM is a straightforward process that a confident DIYer can handle. While locations vary slightly, the steps are generally the same.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Module: On the Cavalier and Sunfire, the PCM is typically found in the engine compartment on the passenger side, near the firewall or strut tower. On the Grand Am and Alero, it’s often located inside the vehicle, behind the left side of the center dash.
- Disconnect the Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Inspect the pins for any corrosion or damage.
- Remove the Old PCM: Unbolt the mounting hardware holding the old computer in place and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed module in the same location, secure the hardware, and firmly reconnect the wiring harnesses until they click into place.
- Final Step: Reconnect the negative battery terminal. The vehicle may need to complete a drive cycle for all monitors to be ready, but it should start and run correctly immediately.
