Is Your Saturn Sky Running Rough?
If your 2008, 2009, or 2010 Saturn Sky is experiencing perplexing issues like a persistent check engine light, erratic engine behavior, stalling, or a complete no-start condition, the culprit is often a failing Powertrain Control Module (PCM). 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 begins to fail, it can create a cascade of problems that are difficult to diagnose.
This replacement PCM, service number 12629019, is the definitive solution to restore your vehicle’s performance and reliability. It arrives at your door fully programmed with the latest GM software updates, specifically calibrated to your vehicle’s unique Vehicle Identification Number (VIN). This eliminates the need for expensive dealership programming and allows for a more straightforward installation process. Simply provide your VIN after purchase, and we handle the complex programming for you.
From the Diagnostic Bay
We once had a 2009 Saturn Sky 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. After hours of chasing wires and checking sensors, we finally tested the driver circuit within the original PCM. We found it was intermittently failing, not sending a consistent signal to the coil. Installing a correctly programmed PCM solved the issue instantly. It’s a classic case of symptoms pointing to one thing, while the root cause lies within the vehicle’s central computer.

Frequently Asked Questions
Do I need to do any programming after I receive this PCM?
No. We program the module with the latest GM calibrations using the VIN you provide before we ship it. However, you will need to perform a security relearn procedure once it’s installed. This is a simple process that can be done without special tools and typically takes 10-30 minutes. Instructions are readily available online for your specific vehicle.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. You can find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this compatible with other GM vehicles?
Yes, this PCM is compatible with a wide array of GM models and engines, including the Chevrolet Cobalt, HHR, Malibu, Silverado 1500, Pontiac G5, G6, Solstice, and more. Please check the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
What if I have the wrong part number?
This unit replaces several common service numbers, such as 12597125, 12629019, and 12635902. As long as your vehicle is on our compatibility list, this module will function correctly once programmed to your VIN, even if the service number on your old unit is different.
What is a security relearn procedure?
The security relearn, also known as a key relearn or anti-theft relearn, syncs the new PCM with your vehicle’s existing anti-theft system and keys. For most GM vehicles of this era, the procedure involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows the components to communicate and authorize the new module.
