Restore Peak Performance to Your Vehicle
Is your Chevrolet Impala, or another compatible GM vehicle, suffering from perplexing issues like stalling, poor fuel economy, a persistent Check Engine Light, or a no-start condition? These are often the tell-tale signs of a failing Engine Control Module (ECM). As the central computer of your vehicle’s powertrain, a faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting. This replacement Engine Control Module, part number 12607096, is the definitive solution to restore your vehicle’s reliability and drivability.
From the Diagnostic Bay
We had a 2008 Chevy Impala SS come into the shop that was driving the owner crazy. It would run fine for a week, then suddenly start misfiring and losing power, throwing random communication codes that didn’t point to a specific sensor. The owner had already replaced the spark plugs, wires, and a couple of sensors with no luck. After hours of chasing electrical gremlins, we hooked up our scope to the main data lines and saw the signal from the ECM was noisy and inconsistent. We swapped in one of our pre-programmed modules, matched to the car’s VIN. After a quick security relearn, the car started up and ran perfectly smooth. The owner called a month later to say it hadn’t missed a beat. A faulty computer can mimic dozens of other problems, and a properly programmed replacement is often the fastest, most reliable fix.
Symptoms of a Failing 2008-2009 Impala ECM
If you’re experiencing any of the following issues, your ECM may be the culprit. A failing module can cause intermittent problems that are difficult to diagnose, but these are the most common indicators:
- ✔ Check Engine Light is on or flashes intermittently
- ✔ Engine stalling or shutting off while driving
- ✔ Noticeable decrease in fuel efficiency
- ✔ Rough idling or engine misfires
- ✔ Car won’t start, even with a good battery and starter
- ✔ Transmission shifting issues or harsh engagement
- ✔ Communication errors with diagnostic scan tools

Frequently Asked Questions
Do I need to get this ECM programmed?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will load the correct, updated software for your specific car.
What is a security relearn procedure?
A security relearn, or anti-theft relearn, syncs the new ECM with your vehicle’s existing anti-theft system and keys. It’s a simple procedure that typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. Instructions are readily available online for your specific model.
Where is the ECM located on a 2008-2009 Impala?
On the 2008-2009 Chevrolet Impala, the Engine Control Module is typically located inside or underneath the air cleaner box assembly in the engine bay. Always disconnect the battery before attempting to remove or install the module.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM part. Each unit is inspected to ensure it meets strict performance standards before being programmed and shipped.
Will this fix my car’s problem for sure?
While this ECM is the solution for a faulty module, it’s crucial to ensure your vehicle has been properly diagnosed. A failing ECM can mimic other issues, such as bad sensors or wiring problems. We recommend a professional diagnosis to confirm the ECM is the root cause of your issues.
