The ECU communicates with various sensors in the engine to gather data on operating conditions. The PCM interprets this data and makes adjustments to the engine and transmission systems accordingly. The ECM monitors engine performance and makes real-time adjustments to maintain optimal operation. By understanding the roles of these control modules, you can better appreciate the complexity of your car's internal systems and how they contribute to its overall performance. ...
