Restore Peak Performance to Your Vehicle’s Engine
If you’re dealing with frustrating engine problems in your 2010 Saturn VUE—like stalling, poor fuel economy, a persistent check engine light, or a no-start condition—a failing Engine Control Module (ECM) is often the culprit. As a technician with over 20 years of experience, I’ve seen firsthand how a faulty ECM can cause a cascade of confusing issues. This replacement Engine Computer, part number 12625455, is the reliable, straightforward solution to get your vehicle running smoothly again.
What sets this part apart is our essential pre-programming service. Before we ship your module, we flash it with the latest official GM software, specifically matched to your vehicle using your VIN. This means you can skip the expensive and time-consuming trip to the dealership for programming. This isn’t just a part; it’s a complete, ready-to-install solution designed to restore the precise control your engine needs for optimal power, efficiency, and reliability. Getting the right 2010 VUE Engine Computer is critical, and this professionally prepared module ensures a perfect match.
From the Diagnostic Bay: The Intermittent No-Start Mystery
A customer brought in a 2010 Saturn VUE with a 3.5L engine that would intermittently refuse to start. There were no consistent trouble codes, just a frustrating ‘crank-no-start’ situation that would happen without warning. After checking fuel pressure, spark, and all the usual suspects, we hooked up a high-end scanner to monitor live data from the ECM. We noticed that during the no-start events, the ECM would lose communication with other key modules. This pointed directly to an internal failure within the computer itself. We replaced it with a pre-programmed module like this one. The installation took less than 30 minutes, and the vehicle started perfectly every time afterward. It’s a classic example of how a failing ECM can create ghost-like problems that are solved with a quality replacement.
Is Your Vehicle Showing These ECM Failure Signs?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, it might be time for a replacement:
- ✔ Check Engine Light is on with codes like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or other communication errors.
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained drops in fuel economy.
- ✔ Rough or inconsistent idling.
- ✔ Stalling or hesitation during acceleration.
- ✔ Automatic transmission shifting issues.
- ✔ Loss of power and poor overall performance.
A Straightforward Guide to Installation
Installing your new 2010 VUE Engine Computer is a manageable job for a DIYer with basic tools. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to ensure the system is fully powered down.
- Locate the ECM: On the 2010 Saturn VUE, the Engine Control Module is typically found in the engine compartment. Consult your vehicle’s service manual for the exact location.
- Disconnect the Old Module: Carefully unplug the electrical connectors. These often have locking tabs that need to be released. Never force them. Once disconnected, unbolt the old ECM from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed ECM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Reconnect Power: Reattach the negative battery terminal. The vehicle may need to go through a brief idle relearn procedure, which usually involves letting it idle for a few minutes.

What is VIN programming and why is it important?
What is VIN programming and why is it important?
VIN programming is the process of loading your vehicle’s specific software onto the engine computer. This software is tied to your unique 17-digit Vehicle Identification Number (VIN) and controls everything from fuel mixture and ignition timing to transmission shifting and anti-theft systems. Without correct VIN programming, the module will not function correctly in your vehicle. We handle this for you before shipping.
Is this part truly ‘plug-and-play’?
Yes. Because we program the module to your VIN before it ships, it arrives ready to install. In most cases, no further programming or dealer visits are required. You simply install the part, and you’re ready to go. Some vehicles may require a simple security or idle relearn procedure, which can be done without special tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (like codes P0601-P0606), then yes, this part will resolve the issue. However, if the light is on for another reason (e.g., a faulty oxygen sensor), you will still need to diagnose and repair that separate problem. A proper diagnosis is always recommended before replacing any parts.
My original part number is 12629009. Will this work?
Yes, this engine computer is a fully compatible replacement for original part numbers 12625455 and 12629009. It will function identically to the original part once programmed for your vehicle.
