Restore Peak Performance to Your Saturn VUE
Is your 2002-2007 Saturn VUE running rough, stalling unexpectedly, or showing a persistent Check Engine Light? These are common indicators of a failing Engine Control Module (ECM), the central computer responsible for managing your vehicle’s engine performance, fuel efficiency, and emissions. A faulty ECM can lead to a cascade of frustrating and potentially damaging issues. This replacement ECM, part number 12202143, is the definitive solution to get your VUE back on the road, running as it should.
From the Diagnostic Bay
We once had a 2005 Saturn VUE come into the shop that had its owner completely stumped. He had replaced the spark plugs, ignition coils, and even the mass airflow sensor trying to chase down a random misfire and terrible gas mileage. The codes were inconsistent, and the engine just felt ‘lazy.’ After connecting our diagnostic scanner and monitoring the live data, we noticed the fuel trim values were erratic and the injector pulse width was jumping all over the place. This pointed directly to the processor in the ECM. We installed one of our pre-programmed modules, and the VUE immediately smoothed out. It’s a classic case where chasing sensors costs more time and money than addressing the root cause: the vehicle’s main computer.
Is Your Saturn VUE Showing These Symptoms?
A failing ECM can manifest in various ways. If you’re experiencing any of the following, your engine computer is the likely culprit:
- ✔ Persistent Check Engine Light (CEL) on your dashboard.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy (MPG).
- ✔ Rough or erratic idling.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Transmission shifting issues or harsh shifts.
- ✔ Failure to pass state emissions tests.
- ✔ Inaccurate or non-functional dashboard gauges.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before the part is shipped. By providing your VIN during checkout, you will receive a module that is fully programmed and ready for installation. This saves you the time, cost, and hassle of a dealership appointment.
What happens if I install it without programming?
An unprogrammed ECM will not work correctly. Critical systems, including the anti-theft system (Passlock/VATS), fuel injectors, and ignition timing, will not function. This will result in a no-start condition. Our pre-programming service ensures your vehicle will start and run correctly once the module is installed.
Where can I find my vehicle’s VIN?
Your 17-digit VIN can be found in several places: on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward. The ECM is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. We always recommend consulting a repair manual for your specific vehicle or seeking help from a qualified mechanic if you are unsure.
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 and allow the light to be cleared. However, it’s essential to ensure the codes have been properly diagnosed, as the light could be on for other reasons, such as a bad sensor or wiring issue.
