Is Your Chevy HHR Running Erratically?
If you’re dealing with a frustrating no-start condition, rough idling, stalling, or a persistent check engine light in your 2006 Chevrolet HHR, a failing Engine Control Module (ECM) is a very likely culprit. These issues can disrupt your daily routine and compromise your vehicle’s reliability. This professionally programmed ECM is the definitive solution, designed to restore your vehicle’s performance and get you back on the road with confidence.
Common HHR ECM Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often making diagnosis difficult. If you’re experiencing any of the following, this module is your answer:
- Check Engine Light: Specifically for communication errors or internal processor faults (e.g., DTC P0601, P0606).
- Stalling or Misfiring: The engine may cut out unexpectedly or run poorly, indicating incorrect fuel and spark commands.
- No-Start Condition: The engine cranks but won’t start because the ECM isn’t properly managing the ignition or fuel systems.
- Poor Fuel Economy: Inefficient engine operation caused by incorrect sensor readings or outputs.
- Communication Issues: Your mechanic’s scan tool cannot communicate with the engine computer.
We solve these problems by providing a fully tested and properly configured programmed 2006 Chevy HHR ECM. We take the guesswork out of the repair by flashing the unit with the latest GM software updates and calibrating it specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures a seamless installation process without requiring a trip to the dealership.

Expert Insight: Why VIN Programming is Non-Negotiable
As a veteran tech, I’ve seen countless DIY repairs go wrong because of a mismatched computer. On modern vehicles like your HHR, the ECM is the brain of the operation, and it’s tied directly to the anti-theft system (VATS/Passlock). You can’t just pull a module from another car and expect it to work; the vehicle will not start. Our VIN programming service syncs this module to your specific vehicle, ensuring all components communicate correctly, including the ignition and security systems. This is the only way to guarantee a successful and lasting repair without expensive dealer intervention.
Don’t let a faulty computer keep your reliable HHR off the road. This is the straightforward, professional solution you need. By ordering this programmed 2006 Chevy HHR ECM, you’re not just buying a part; you’re investing in a reliable fix that restores your vehicle’s health and your peace of mind.
Frequently Asked Questions
What do I need to do after I purchase?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot ship your part until we have this information, as we use it to program the module specifically for your HHR.
Is any additional programming required once I install it?
No. The unit arrives fully programmed and ready for installation. In some cases, a simple “Crankshaft Variation Relearn” procedure may be needed, which can be performed with a compatible scan tool or by following a specific drive cycle. This is a simple calibration, not a full programming session.
How do I know this will fix my car’s problem?
This ECM is a direct solution for issues originating from a faulty engine computer. While it resolves the common symptoms listed, we always recommend having a qualified mechanic perform a full vehicle diagnosis to confirm the ECM is the point of failure before ordering.
Is this compatible with a 2005 Cobalt or Pursuit?
Yes, this module is also a compatible replacement for the 2005-2006 Cobalt and Pursuit models equipped with the 2.2L engine and matching service numbers listed in the description.
What is the difference between an ECM and a PCM?
ECM (Engine Control Module) and PCM (Powertrain Control Module) are often used interchangeably. A PCM controls both the engine and the transmission, while an ECM typically controls only the engine. For your vehicle, this module manages the full powertrain and serves as the primary computer.
