Is Your 2006 HHR Running Rough or Not Starting at All?
If you’re dealing with frustrating engine problems in your 2006 Chevy HHR, the Engine Control Module (ECM) is often the hidden culprit. As a mechanic with over two decades of experience under the hood, I’ve seen countless vehicles sidelined by a faulty ECM. Itโs the brain of your engine, and when it starts to fail, the symptoms can be confusing and widespread, making diagnosis a real challenge for the average owner.
From the Shop Floor: A Real-World HHR Diagnosis
“A customer’s 2006 HHR came in last week with these exact symptoms. It would crank but not start, and when it did, it ran terribly and threw a dozen unrelated codes. The owner had already replaced the battery and spark plugs. We hooked up our professional scan tool and couldn’t establish a solid connection with the ECMโa classic sign of an internal failure. After verifying power and ground to the module located in the left rear of the engine compartment, we confirmed the ECM itself was the issue. Heat and vibration had taken their toll on the internal circuit board. This isn’t just a theory; it’s a common failure point I’ve diagnosed hundreds of times on this GM platform.”
Common Symptoms of a Failing HHR ECM
A bad engine computer can manifest in numerous ways. If you’re noticing any of the following, it’s time to consider the ECM as the source of your problems:
- โ Check Engine Light is on with multiple, seemingly random trouble codes.
- โ The engine cranks but refuses to start.
- โ Noticeable drop in fuel economy for no apparent reason.
- โ Rough or erratic idling, stalling, and poor acceleration.
- โ Transmission shifting issues or harsh engagement.
- โ Communication errors when trying to use an OBD-II scanner.
- โ The anti-theft or security light stays illuminated, preventing the car from starting.
