Is Your Saturn VUE Running Rough? The ECM Might Be the Culprit.
If your 2002-2007 Saturn VUE is suffering from perplexing issues like stalling, erratic idling, a persistent Check Engine Light, or even a no-start condition, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel delivery and ignition timing to emissions controls and transmission shifting. When it begins to fail, the symptoms can be widespread and frustrating to diagnose. This replacement ECM, compatible with part numbers 22681967 and 12202143, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2005 Saturn VUE with the 2.2L engine come into the shop on a tow truck. The owner had already replaced the fuel pump and crankshaft position sensor trying to solve an intermittent no-start problem. The vehicle would crank but wouldn’t fire up, and then an hour later, it would start like nothing was wrong. After hooking up our diagnostic scanner, we noticed intermittent communication loss with the main computer. We checked the power and ground circuits to the module, and they were solid. Tapping on the ECM housing with a screwdriver handle would sometimes cause the engine to stall. This confirmed our suspicion: the internal circuits of the original ECM were failing. We installed one of our pre-programmed modules, and the VUE fired up instantly and ran perfectly. It’s a classic case where the central computer was the hidden cause of a seemingly unrelated problem.
Common Symptoms of a Failing VUE ECM
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine stalls unexpectedly or struggles to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or erratic engine idle.
- ✔ Poor acceleration and overall loss of power.
- ✔ Automatic transmission shifts harshly or at the wrong times.
- ✔ Complete failure to communicate with diagnostic scan tools.

This commitment to quality means you get a reliable part that solves your problem correctly the first time.
Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install. This is a true plug-and-play solution.
Where is the ECM located on my 2002-2007 Saturn VUE?
The ECM on the Saturn VUE is typically located in the engine compartment, on the driver’s side, near the firewall or strut tower. It’s a silver metal box with several large electrical connectors.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by a faulty ECM, then yes, this part will resolve the issue. It’s crucial to ensure the underlying problem isn’t a separate faulty sensor or wiring issue. However, many vague or communication-related codes point directly to the ECM.
Is this compatible with both part numbers 22681967 and 12202143?
Yes, this module is a direct replacement for both OEM part numbers 22681967 and 12202143. We program the hardware to function identically for your specific vehicle.
What information do you need from me?
All we need is your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
