Is Your Chevrolet HHR Running Rough?
A failing Engine Control Module (ECM) can be the source of countless frustrating and difficult-to-diagnose issues. If your 2006 HHR is experiencing erratic behavior like stalling, poor fuel economy, a persistent check engine light, or even a no-start condition, the vehicle’s central computer may be the culprit. The ECM is the brain of your engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it fails, the entire system’s performance suffers, leaving you with an unreliable vehicle.
This is a direct replacement Engine Control Module, service part number 12607096, designed to restore your vehicle’s performance and reliability. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle using your VIN. This ensures that it has the latest software updates from GM, which often correct underlying drivability issues the factory identified after the vehicle was built. You receive a component that is ready for installation, eliminating the need for expensive trips to the dealership for programming.

Before replacing your ECM, always perform a thorough check of the basics. Ensure your battery is fully charged and the terminals are clean and tight. Inspect the main power and ground wires connected to the ECM and the engine block for corrosion or damage. A poor ground connection is a common issue that can mimic the symptoms of a failed computer, and it’s a much simpler and cheaper fix!

The Importance of VIN Programming
Modern vehicles are complex, and the ECM must be perfectly matched to your car’s specific options, emissions standards, and security system. Ordering a generic, non-programmed module will result in a vehicle that won’t start or run correctly. Our process eliminates this problem. By providing your VIN during checkout, you guarantee that the module you receive is calibrated precisely for your 2006 HHR. This VIN-specific programming ensures all systems communicate correctly, from the engine and transmission to the anti-theft system, for a seamless installation process.
