Is Your 2006 HHR Running Rough? The Engine Module Might Be the Culprit.
If your 2006 Chevrolet HHR is experiencing frustrating issues like a persistent check engine light, stalling, poor fuel economy, or a no-start condition, a failing Engine Control Module (ECM) is a likely cause. As the central computer of your vehicle’s powertrain, the ECM is responsible for managing everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it fails, the symptoms can be widespread and difficult to diagnose, leaving you stranded and facing expensive dealership repair bills.
This is a direct-replacement Engine Control Module, service part number 19210737, for your 2006 HHR. We take the guesswork and hassle out of the repair process. Unlike parts from a salvage yard that require costly programming, this unit arrives at your door flashed with the latest GM software updates, specifically matched to your vehicle using the VIN you provide. This ensures seamless integration and restores your vehicle’s original performance and reliability.
From the Diagnostic Bay
We had a 2006 HHR come into the shop with a classic complaint: intermittent stalling at stoplights and a check engine light that kept coming back for a random misfire. The owner had already replaced the spark plugs, ignition coil pack, and even a camshaft position sensor based on advice from forums. The problem persisted. After hooking up our professional scan tool, we noticed that the live data for fuel trims was erratic and communication with the module would occasionally drop. This pointed directly to an internal fault in the ECM. We installed a VIN-programmed 2006 HHR Engine Module, performed the security relearn procedure, and the car ran perfectly. It’s a great reminder that sometimes the ‘brain’ is the problem, not the parts it’s controlling.
Common Symptoms of a Failing ECM

- ✔ Engine stalling or shutting off while driving
- ✔ Rough or erratic idling
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Hesitation or stumbling during acceleration
- ✔ Transmission shifting problems or harsh shifts
- ✔ Error codes that won’t clear or return immediately after clearing

Frequently Asked Questions
Is this ECM ready to install?
Yes! This ECM comes pre-programmed to your vehicle’s specific VIN. In most cases, you will only need to perform a simple security relearn procedure (often called a key relearn), which can be done without any special tools. Instructions are readily available online for your specific model.

After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Will this fix my car’s problem for sure?
While this module corrects issues caused by a faulty ECM, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other faulty sensors or mechanical issues. We recommend a professional diagnosis before ordering.

What is an ECM?
The Engine Control Module (ECM), also known as the Powertrain Control Module (PCM) or Engine Control Unit (ECU), is a computer that acts as the ‘brain’ of your vehicle’s engine. It controls fuel injection, ignition timing, and other critical functions to ensure optimal performance and efficiency.
