What happens if your ECM is not working?
A faulty ECM disallows your engine from knowing how much fuel to burn in the combustion process. Typically, the vehicle consumes more fuel than it should in this situation. You’ll end up paying more for gas than you would with a functioning ECM. The ECM plays a vital role in engine performance.
What happens if the engine control module fails?
If the ECM fails completely, it will leave the vehicle without engine management control, and will not start or run as a result. The engine may still crank, but it will not be able to start without the vital inputs from the computer.
How does the engine control module ( ECM ) work?
The ECM takes the information from the engine’s various sensors, and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. The ECM plays a crucial role in newer vehicles, where many (if not all) of the essential functions of the car are controlled by the ECM.
Can a bad ECM cause a car to stall?
Engine Stalling or Misfiring Erratic engine behavior may also indicate a bad or failing ECM. A faulty computer may cause the vehicle to intermittently stall or misfire. The symptoms might come and go and not appear to have any sort of pattern to their frequency or severity. 3. Engine Performance Issues
How to reset the engine control module ( ECU )?

Why does my ECM log an error code?
When an issue arises, the ECM will log an error code that lets you know the source of the problem. This can be advantageous since you can determine the exact cause of failure. It can also be inconvenient since you’ll need a mechanic with an expensive computer to read the error code.
Can a bad ECM cause a stick shift?
The ECM doesn’t control the transmission on a stick shift, so if you’re having problems with your five-speed, it’s the transmission. If you’ve done numerous repairs on the transmission and replaced your automatic transmission fluid and you’re still having problems, the ECM could be at the root of your problems.
