Restore Peak Performance to Your Vehicle
If your 2006 Chevrolet Impala is experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle’s engine management system, responsible for precisely controlling fuel mixture, ignition timing, and transmission shifting. When it fails, it can cause a wide range of drivability problems that can leave you stranded. This direct-replacement ECM is the definitive solution to get your vehicle running smoothly and reliably again.
We had a 2006 Impala 3.5L come into the shop with a complaint of intermittent stalling and a P0601 internal controller memory error code. The customer had already replaced the spark plugs and an oxygen sensor trying to solve the problem. After verifying the power and ground circuits to the ECM were solid, we knew the module itself was the issue. We installed one of our VIN-programmed units, performed a quick security relearn, and the car ran perfectly. The customer was thrilled to have their reliable daily driver back without an expensive trip to the dealership.
Is Your Engine Computer Failing?
A faulty ECM can manifest in numerous ways, often mimicking other component failures. Diagnosing the root cause is key to avoiding unnecessary repairs. This replacement 2006 Impala ECM is the solution for a vehicle exhibiting these common symptoms.
- ✔ Check Engine Light is on with communication-related or internal processor fault codes.
- ✔ Engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or unpredictable engine performance, including stalling and misfires.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass emissions testing.
- ✔ Intermittent issues that seem to have no other logical cause.

Don’t waste time and money at a dealership for programming services. We take the hassle out of the repair process. When you purchase this module, you simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN).

This ensures that the ECM communicates flawlessly with your engine, transmission, anti-lock brake system, and security system right out of the box. Installation is straightforward for any competent DIY mechanic. In most cases, a simple security relearn procedure (which you can do yourself) is all that’s needed to complete the job.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. This ECM comes fully programmed to your vehicle’s specific VIN before we ship it. This saves you the time, cost, and hassle of a trip to the dealership. It’s ready for installation upon arrival.
Where is the ECM located on my 2006 Impala?
On the 2006 Chevrolet Impala with the 3.5L or 3.9L engine, the ECM is typically found bolted to the lower part of the air cleaner box assembly in the engine bay. Always disconnect the battery before attempting removal or installation.
What happens if I forget to provide my VIN?
Providing your VIN is a required step for this purchase. We cannot program or ship the module without it, as it would not function correctly in your vehicle. We will contact you after your purchase to ensure we have the correct information.
Will I need to perform any other steps after installation?
In many cases, you may need to perform a simple security relearn procedure, also known as a VATS relearn. This process syncs the new ECM with your vehicle’s existing keys and can be done without any special tools. Instructions are readily available online or in service manuals.
Will this part fix my check engine light?
If your check engine light is caused by a faulty ECM (indicated by codes like P0601, P0606, or other communication errors), then this replacement module will solve the problem. However, it’s crucial to properly diagnose the codes first to ensure the ECM is the true source of the issue.
