Electronic Control Unit (ECU), Powertrain Control Module (PCM), and Engine Control Module (ECM) are all terms used to refer to the central computer system in your vehicle that controls various functions related to the engine and transmission.

Sensors: The ECU collects data from sensors like the oxygen sensor, mass airflow sensor, and throttle position sensor to monitor the engine's condition.

Calculations: Using the input from sensors, the ECU calculates the ideal air-fuel mixture, spark timing, and other parameters to maximize engine performance.

Output: The ECU sends signals to various components, such as the fuel injectors and ignition coils, to make adjustments based on the data received.

Why is maintaining your ECU important?

PCM: The PCM is responsible for coordinating the functions of the engine, transmission, and other powertrain components. It acts as the brain of the vehicle, ensuring seamless communication and operation of these systems.

ECM: The ECM is similar to the PCM but may have a narrower focus on engine-related functions. It monitors and controls various engine parameters to ensure optimal performance and efficiency.

Common Issues with ECU, PCM and ECM
