Understanding these crucial components of your vehicle's engine control system is essential to keep your car running smoothly. In this comprehensive guide, we will delve into the ins and outs of these control modules, providing you with all the information you need to know.

The ECU is responsible for managing the engine's performance by monitoring various sensors and adjusting fuel injection, ignition timing, and other parameters.

It plays a crucial role in optimizing fuel efficiency, emissions, and overall engine performance.

Issues with the ECU can lead to poor engine performance, decreased fuel efficiency, and potential safety hazards.

Powertrain Control Module (PCM)

Check Engine Light: A persistent check engine light could indicate a problem with the ECU, PCM, or ECM. Use a diagnostic tool to retrieve error codes and Sensor Calibration identify the issue.

Poor Fuel Efficiency: If your car is burning more fuel than usual, the ECU or PCM may need recalibration or reprogramming to optimize fuel delivery.

Engine Stalling or Rough Running: A faulty ECM or PCM can cause engine stalling, misfiring, or rough idling. Inspect wiring connections and sensors to diagnose the problem.

Transmission Malfunctions: Issues with the PCM can lead to transmission problems, such as shifting delays or harsh gear changes. Consult a professional to diagnose and repair the PCM.
