Is Your GM Vehicle Experiencing Engine Problems?
If your Saturn Vue, Chevy Malibu, or another compatible GM vehicle is suffering from erratic behavior, poor fuel economy, a persistent check engine light, or even a no-start condition, a failing Powertrain Control Module (PCM) is often the 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 confusing and frustrating issues that can be difficult to diagnose.
From the Diagnostic Bay
We once had a 2009 Chevy HHR come into the shop with a persistent misfire on cylinder 3. The owner had already replaced the spark plug, ignition coil, and fuel injector, but the problem remained. Diagnostic scans showed inconsistent injector pulse width commands. After confirming the wiring harness was intact, we suspected the PCM. Swapping in a known-good, correctly programmed module like this one instantly solved the issue. The original PCM’s driver for that injector had failed internally—a classic example of how a bad module can mimic a mechanical or sensor failure, costing you time and money on unnecessary parts.
Diagnosing Your 2008-2010 VUE PCM
A faulty PCM can manifest in numerous ways, often mimicking other component failures. This replacement module, part number 12635902, is the definitive solution for a wide range of electrical and performance problems. By providing us with your vehicle’s Vehicle Identification Number (VIN), we flash the module with the latest factory software specific to your car, ensuring a seamless and correct installation process. This eliminates the need for expensive dealership programming and gets you back on the road faster.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Unexplained drop in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start or intermittent starting issues.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Failure to pass state emissions tests.
This module is a direct replacement for multiple service numbers, including 12597125, 12612397, 12612397, 12594750, 12629019, and 12611549. It fits a broad array of GM vehicles beyond the Saturn Vue, such as the Chevrolet Silverado, Cobalt, HHR, Malibu, Impala; GMC Sierra; Pontiac G5, G6, Solstice; and Buick Lucerne. Our programming service ensures that this versatile part functions precisely as intended for your specific make, model, and engine configuration.
Don’t let a faulty computer keep your car off the road. This professionally prepared 2008-2010 VUE PCM is your plug-and-play solution to restore your vehicle’s reliability, performance, and efficiency.
Do I need to get this PCM programmed?
No. This module comes fully programmed to your vehicle’s specific VIN. Simply provide your VIN to us after purchase, and we will flash the unit with the latest GM software before shipping. It arrives ready for installation.
What is a CASE Relearn and will I need one?
A CASE (Crankshaft Angle Sensor Error) relearn procedure may be required after installation. This synchronizes the new PCM with your engine’s crankshaft position sensor. Most mid-level diagnostic scan tools can perform this procedure in a few minutes. In many cases, the vehicle will run fine without it, but you may have a lingering check engine light until the procedure is completed.
Where is the PCM located on my vehicle?
The location varies by model. For many vehicles like the Chevy Cobalt or Pontiac G6, it’s in the front LH (driver’s side) of the engine compartment. On trucks like the Silverado/Sierra, it’s often found under the battery tray. For vans, it may be in the rear of the engine compartment. Always consult a service manual for your specific vehicle to confirm the location before beginning work.
How do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on the vehicle itself. Look for a small metal plate on the driver’s side of the dashboard visible through the windshield, or on the sticker inside the driver’s side door jamb.
Will this part fit other GM vehicles?
Yes. While this is a primary fit for the 2008-2010 Saturn VUE, this PCM service number is compatible with dozens of other GM models, including various years of the Cobalt, HHR, Malibu, G5, G6, Silverado, Sierra, and more. Our VIN programming ensures it works correctly for any vehicle on the compatibility list.
