Can a knock sensor cause a car ECM to fail?

There’s also a knock sensor on the engine itself. While these sensors aren’t likely to cause any catastrophic problems, failures in these areas can cause your ECM to make unnecessary adjustments that affect your car’s performance. In these cases, though, the problem is usually with the sensors, and not with the ECM.

How does the ECM work in a car?

Your car’s Engine Control Module (ECM) monitors all the sensors in the vehicle to make sure that the car’s systems are running as they’re supposed to. When conditions change, the ECM will automatically make adjustments in real time. That is why it is so important to recognize the symptoms of ECM failure.
