The computer governs crucial functions like air fuel mixture, electronic valve control, idle speed, and variable valve timing. It manages these systems by reading values from engine bay sensors, interpreting this data using lookup tables, and adjusting internal combustion engine actuators accordingly.

Engine control modules, or units, replace a series of mechanical and pneumatic settings, meaning they can make more efficient adjustments based on real data from the engine bay sensors. The module is crucial to engine performance, and a malfunctioning part can lead to decreased fuel economy and a host of other issues.

Engine computer issues can be an ordeal to troubleshoot. In addition to its influence in far reaching functions, the computer relies on sensors to behave properly. The part also has a lot of different names; an engine computer that is integrated with the transmission control unit (TCU) is called a powertrain control module (PCM). All this can make it hard to diagnose when something has gone wrong. If you think the computer may be broken, see if you can determine the cause. Typically, ECU/ECM/PCM failure is caused by voltage overload from a short circuit or environmental damage from corrosion, hot components, or vibration. Water is particularly dangerous for engine computers.

When it’s time to equip your vehicle with a new ECM or ECU, come to AutoZone. We carry parts for all major vehicles, and we make finding the right parts easy. Enter your vehicle’s year, make, and model up above, and we will take it from there.
