Restore Peak Performance to Your Chevrolet Volt
The Engine Control Module (ECM), often called the Powertrain Control Module (PCM), is the central computer for your 2011-2015 Chevrolet Volt’s gasoline engine. It meticulously manages critical functions like fuel injection, ignition timing, and emissions systems. When the ECM begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose issues, from a simple check engine light to a vehicle that won’t start at all. This replacement ECM, part number 22819494, is the definitive solution to restore your vehicle’s original performance and reliability.
From the Diagnostic Bay
We had a 2013 Volt come into the shop with a complaint of intermittent stalling when the gasoline engine kicked on. There were no consistent trouble codes, just a generic U-code for lost communication that would appear and disappear. After hours of checking wiring harnesses and grounds, we finally isolated the issue to the ECM itself. The internal processor was failing under load, causing it to briefly drop communication with the other modules. Installing a VIN-programmed replacement like this one solved the problem instantly. The customer went from being frustrated with an unreliable car to having their dependable Volt back on the road.
Is Your 2011-2015 Volt Engine Control Module Failing?
A faulty ECM doesn’t always fail completely. It can degrade over time, leading to a variety of symptoms that can be mistaken for other mechanical problems. If you’re experiencing any of the following, a failing ECM could be the culprit.
Common Symptoms of a Bad ECM
- ✔ Check Engine Light is on with various trouble codes (DTCs)
- ✔ Engine cranks but will not start
- ✔ Rough or unstable idle
- ✔ Noticeable decrease in fuel economy
- ✔ Intermittent stalling or hesitation during acceleration
- ✔ Transmission shifting issues or harsh shifts
