Is Your Buick Regal or GM Vehicle Acting Up?
A failing Engine Control Module (ECM), often called the engine computer, is the root cause of many frustrating and difficult-to-diagnose vehicle problems. As the central command center for your engine, the ECM controls everything from fuel mixture and ignition timing to transmission shifting and emissions systems. When it starts to fail, it can create a cascade of issues that can leave you stranded. If you’re experiencing erratic engine behavior, a persistent Check Engine Light, or a no-start condition, a faulty ECM could be the culprit.
This genuine OEM Engine Control Module, part number 12667002, is the definitive solution for restoring your vehicle’s performance, reliability, and efficiency. We take the guesswork and high cost out of the equation by pre-programming the module specifically for your vehicle using your VIN. This means it arrives at your door with the latest GM software updates, ready for installation, saving you a costly and time-consuming trip to the dealership.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light: The most common symptom, often with confusing or multiple diagnostic trouble codes (DTCs).
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM struggles to manage ignition and fuel.
- ✔ No-Start Condition: The vehicle may crank but fail to start because the ECM isn’t commanding the fuel injectors or ignition coils to fire.
- ✔ Poor Fuel Economy: An inefficiently running engine, due to incorrect fuel and air calculations from a faulty ECM, will consume more fuel.
- ✔ Performance Issues: You may notice a significant loss of power, poor acceleration, or hesitation.
- ✔ Inconsistent Shifting: The ECM works with the Transmission Control Module (TCM), and a failure can lead to harsh or erratic automatic transmission shifting.
- ✔ Failed Emissions Test: The ECM is critical for managing your vehicle’s emissions systems. A malfunction will almost certainly cause a failed smog check.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN at checkout, and the module will arrive ready for installation with the latest GM software.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the ECM with the exact software and calibration file for your vehicle’s specific options and systems.
Is this a difficult part to install?
The physical installation is typically straightforward, involving disconnecting the battery and removing a few bolts and electrical connectors. After installation, a simple security relearn procedure is often required, which can be done without special tools by following a sequence of key turns.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a failing ECM, this part will be the solution. However, it is crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) refer to the same part. PCM (Powertrain Control Module) is a term for a module that controls both the engine and the transmission in one unit. For your vehicle, this part serves as the ECM.
