Is Your 2006 Impala Running Rough? The ECM Might Be the Culprit.

If your Chevrolet Impala is experiencing frustrating issues like stalling, poor acceleration, erratic shifting, or a persistent Check Engine Light, a failing Engine Control Module (ECM) is a very likely cause. The ECM is the central computer of your vehicle, responsible for managing everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it starts to fail, it can create a cascade of problems that are often difficult to diagnose, leading to wasted time and money on unnecessary repairs.

This replacement Engine Control Module, part number 12602044, is the definitive solution to restore your vehicle’s performance and reliability. Unlike generic modules that require expensive programming at a dealership, this unit is professionally flashed with the latest official GM software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at the time of purchase, and we handle the rest. This ensures a seamless installation process and optimal performance right out of the box.

From the Diagnostic Bay

We had a 2006 Impala 3.5L come into the shop with a complaint of intermittent stalling at stoplights and a check engine light that kept coming back for random misfires, even after new plugs and coils. We checked fuel pressure, scanned for vacuum leaks, and tested sensors for hours. Everything seemed to be within spec. On a hunch, we monitored the live data from the ECM and noticed the injector pulse width was fluctuating wildly at idle. We swapped in this pre-programmed ECM, performed the security relearn, and the car immediately idled perfectly. The customer called back a week later to say it hadn’t run that well in years. A faulty computer can mimic dozens of other problems, and having a correctly programmed replacement is often the fastest path to a final repair.

Diagnosing a Faulty 2006 Impala Engine Module

A failing ECM can manifest in numerous ways, making diagnosis tricky. If you’re experiencing any of the following symptoms, it’s time to consider your engine computer as the root cause. This module is the correct solution for these common failures.

  • ✔ Check Engine Light: The most common indicator, often with codes related to sensors, misfires, or communication errors (U-codes).
  • ✔ Engine Stalling or Misfiring: The engine may stall unexpectedly, run rough, or misfire as the ECM fails to properly manage ignition and fuel.
  • ✔ Poor Fuel Economy: Incorrect fuel mixture calculations can lead to a sudden and significant drop in MPG.
  • ✔ No-Start Condition: The vehicle may crank but fail to start if the ECM isn’t activating the fuel pump or ignition system.
  • ✔ Erratic Automatic Transmission Shifting: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifts. A faulty ECM can cause harsh or delayed shifting.
  • ✔ Loss of Power: You may notice a significant decrease in acceleration and overall engine performance.

Plug-and-Play Solution with VIN Programming

The biggest hurdle when replacing a modern vehicle computer is the need for specialized programming. This module eliminates that problem. By providing your VIN, you receive a unit that is a direct-fit replacement, loaded with the correct software for your Impala’s specific engine, transmission, and options. This process ensures all systems communicate correctly and your vehicle operates as the manufacturer intended.

This module is a direct replacement for a wide range of GM service numbers, including: 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. It fits dozens of models beyond the 2006 Impala, making it a versatile and reliable component for many GM cars, trucks, and SUVs from the mid-2000s.

Frequently Asked Questions

Do I need to get this module programmed by a dealer?

No. The main benefit of this part is that we program it for you before shipping. Simply provide your vehicle’s 17-digit VIN during checkout, and the module will arrive with the latest GM software specific to your car, ready for installation.

What is a “security relearn” procedure?

After installing the new ECM, you will need to perform a simple security relearn procedure so the module can recognize your vehicle’s anti-theft system and keys. This procedure does not require any special tools and can typically be done in your driveway in about 30 minutes. Instructions are readily available online or in your vehicle’s service manual.

Where is the ECM located on a 2006 Chevy Impala?

On the 2006 Chevrolet Impala, the Engine Control Module is typically located inside the air filter housing assembly in the engine bay. You will need to remove the top of the air cleaner box to access it.

Will this fix my specific check engine light codes?

This ECM will resolve any codes that are caused by an internal failure of the computer itself. However, it will not fix issues caused by faulty external sensors, wiring, or mechanical components. It is essential to properly diagnose the root cause of your codes before replacing parts.

Is this compatible with other GM vehicles?

Yes. While this listing is focused on the 2006 Impala, this ECM (and its interchangeable service numbers) fits a very wide range of GM vehicles, including models from Buick, Cadillac, Pontiac, Saturn, GMC, and more. Please refer to the detailed fitment list on this page to confirm compatibility with your specific vehicle.
