To help better understand the wiring diagram, we’ll go over the basics of the system, common issues, and tips for troubleshooting.

What is the PCM?

The Powertrain Control Module (PCM) is the main computer for your vehicle. This computer controls many vital systems in the car, including the fuel, transmission, and emissions. It helps to keep all of these parts running smoothly and efficiently. The PCM is part of the overall engine control system, which uses information from sensors to measure things such as engine temperature and speed. The PCM then uses this data to make decisions about how the engine and other parts of the car should operate.
