Restore Peak Performance to Your Saturn SKY
Is your 2008, 2009, or 2010 Saturn SKY suffering from frustrating engine issues like stalling, poor fuel economy, or a persistent Check Engine Light? The Powertrain Control Module (PCM), the central computer of your vehicle, is often the root cause. This vital component manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the symptoms can be widespread and difficult to diagnose. This replacement PCM, part number 12611549, is the definitive solution to restore your vehicle’s original performance and reliability.
We take the guesswork and hassle out of the repair process. Unlike a generic part from a local store, this module is not just a piece of hardware. It’s a complete, plug-and-play solution. Before shipping, we flash the unit with the latest GM-certified software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) during checkout. This ensures that when the part arrives, it’s perfectly matched to your car’s specific configuration, including its engine, transmission, and factory options.
From the Diagnostic Bay
We recently had a 2009 Saturn SKY come into the shop with a very tricky intermittent issue. The owner complained of the car suddenly losing power and stalling at traffic lights, but with no consistent Check Engine codes. After hours of checking fuel pressure, sensors, and wiring, we connected a scope to the PCM’s outputs. We discovered the injector driver circuits were intermittently dropping out due to internal heat soak in the module. We installed one of our VIN-programmed PCMs, performed a quick security relearn, and the car ran perfectly. The customer was thrilled to have their fun-to-drive roadster back without the constant worry of it leaving them stranded. It’s a classic example of how a failing computer can mimic a dozen other mechanical problems.
Is Your Saturn SKY Showing Signs of PCM Failure?
A faulty 2008-2010 Saturn SKY PCM can manifest in various ways. If you’re experiencing any of the following symptoms, a failing engine computer could be the culprit. Proper diagnosis is always recommended, but these are strong indicators that your PCM requires attention.
- ✔ Check Engine Light: The light is on, and you may have codes related to sensors, emissions, or processor faults (e.g., P0601, P0606).
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire, especially as it warms up.
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to a lack of spark or fuel delivery command from the PCM.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG can be caused by incorrect fuel mixture calculations.
- ✔ Failed Emissions Test: The PCM controls the vehicle’s emissions systems, and a fault will almost certainly lead to a failed test.
- ✔ Inconsistent Transmission Shifting: The PCM works with the transmission controller to ensure smooth shifts. Harsh or erratic shifting can be a sign of a bad module.

By providing us with your VIN, you bypass the need for expensive dealership tools or specialized programming services. This 2008-2010 Saturn SKY PCM is a direct-fit replacement for multiple original service numbers, including 12597125, 12612397, 12594750, 12629019, 12635902, and 12611549, ensuring broad compatibility. This module also fits a wide range of other GM vehicles, such as the Cobalt, HHR, Malibu, and G6, which speaks to its proven OEM design and reliability.
Once installed, some vehicles may require a simple, key-on security relearn procedure, which can be done without any special tools. In some cases, a Crankshaft Variation (CASE) relearn may be needed to clear certain codes, which can be performed by most professional scan tools. Get your vehicle back to factory specifications and enjoy the peace of mind that comes with a properly functioning engine computer.
Frequently Asked Questions
Do I need to program this PCM?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN when you place your order, and it will arrive ready to be installed.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to load the correct GM-certified software for your car’s specific engine, transmission, and options.
Is any additional setup required after installation?
In many cases, you will need to perform a security relearn procedure, which typically involves turning the key on and off in a specific sequence. This pairs the new computer to your vehicle’s anti-theft system. A Crankshaft Variation (CASE) relearn may also be necessary to extinguish a check engine light, which can be done with most professional scan tools.
How do I find my vehicle’s VIN?
Your VIN can be found on your vehicle’s registration, insurance card, the driver’s side door jamb sticker, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this part fit other vehicles besides the Saturn SKY?
Yes, this PCM is compatible with a wide range of GM vehicles from the same era, including models like the Chevy Cobalt, HHR, Malibu, Silverado 1500, Pontiac G5, G6, Solstice, and more. Please verify the part number or consult the fitment list to confirm compatibility.
