Restore Your Vehicle’s Core Performance
The Engine Control Module (ECM), often called the Powertrain Control Module (PCM), is the central computer of your vehicle’s engine management system. It meticulously controls fuel injection, spark timing, emissions systems, and transmission shifting to ensure optimal power, efficiency, and reliability. When your original ECM fails, it can lead to a cascade of frustrating and potentially damaging issues. This replacement module, part number 12622141, is the definitive solution to restore the factory performance and drivability of your vehicle. We provide a reliable, pre-programmed 2011 Caprice Engine Module that gets you back on the road without the hassle and expense of dealership programming.
From the Diagnostic Bay
We had a 2011 Caprice PPV (Police Pursuit Vehicle) come into the shop with an intermittent no-start condition and random stalling while driving. The check engine light was on, but the codes were all over the place—U-codes for lost communication, P-codes for sensor circuits, you name it. After hours of chasing wires and checking grounds, we hooked up a scope to the main power and ground feeds at the ECM. We found that the module’s internal voltage regulator was failing under load, causing it to reset randomly. We replaced it with one of these pre-programmed units, and the car fired right up and ran perfectly. The customer was back in service the same day, a testament to how a quality, correctly programmed part can solve even the most complex-seeming electronic issues.
Diagnosing a Faulty 2011 Caprice Engine Module
A failing ECM can manifest in various ways, from subtle performance degradation to a complete no-start situation. If you’re experiencing any of the following symptoms, a faulty engine computer could be the culprit:
- ✔ Check Engine Light: The most common indicator. Codes related to internal module failure (like P0601-P0606) or multiple unrelated sensor codes are strong signs.
- ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM fails to properly control fuel and spark.
- ✔ No-Start Condition: The engine may crank but refuse to start because the ECM is not activating the fuel pump or ignition coils.
- ✔ Poor Fuel Economy: Inaccurate sensor readings or incorrect fuel calculations can cause a sudden and significant drop in MPG.
- ✔ Erratic Transmission Behavior: The ECM works with the Transmission Control Module (TCM). A faulty ECM can cause harsh shifting, failure to shift, or incorrect gear selection.
- ✔ Loss of Communication: A diagnostic scan tool may be unable to communicate with the ECM, indicating a critical internal failure.

Frequently Asked Questions
Do I need to program this module?
No. We program the module to your vehicle’s VIN before shipping. It will arrive ready to install. In some cases, a security or anti-theft relearn procedure may be required after installation, which can typically be done without special tools.
Where do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function correctly in your specific vehicle. We will contact you after your purchase to request the VIN.
Is this a difficult part to install?
For someone with moderate mechanical experience, the installation is typically straightforward. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. However, we always recommend professional installation if you are not comfortable with automotive electronics.
Will this ECM 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 is crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
