From the Diagnostic Bay
We once had a 2006 Impala towed in that had stumped two other shops. It had an intermittent stalling problem that never set a consistent trouble code. The owner had replaced the fuel pump, spark plugs, and multiple sensors. After checking all the basics, we hooked up our scope to monitor the ECM’s command signals to the injectors and ignition coils. We noticed the signals would drop out randomly just before the engine would die. A new, properly programmed ECM was the fix. It’s a perfect example of how a failing module can mimic other issues, making a reliable 2006 Impala ECM Replacement the only true solution.

Frequently Asked Questions
What exactly does the Engine Control Module do?
The ECM is a powerful computer that controls nearly every aspect of your engine’s operation.

Is this part ready to install when I receive it?
Yes! This is the major benefit of our service. We program the module to the specific VIN you provide during checkout. This means it’s ready for a plug-and-play installation, saving you the time and expense of having it programmed at a dealership.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard, visible through the windshield. It may also be on a sticker inside the driver’s door jamb.
Will this fix my car’s specific problem?
While this ECM can resolve the many symptoms listed, proper vehicle diagnosis is always recommended. If your vehicle’s issues are caused by a faulty ECM, this part is the correct solution. We recommend consulting with a professional mechanic or using a diagnostic scan tool to confirm the ECM is the point of failure.
Do I need to send my old ECM (core) back?
