The PCM receives signals from various sensors and switches throughout the vehicle, such as the oxygen sensors, throttle position sensor, and coolant temperature sensor. It uses these inputs to calculate and adjust various parameters, including the air-fuel mixture, ignition timing, and transmission shift points.
The PCM also communicates with other electronic control modules in the vehicle, such as the body control module (BCM) and the anti-lock braking system (ABS) module, to coordinate various functions and ensure overall system performance.
In summary, the PCM is a critical component in the Dodge Neon 2004 that monitors, controls, and adjusts various aspects of the engine and transmission systems to optimize performance and efficiency.
