What is the name of the engine control module?
The engine control module (ECM) is also known as the powertrain control module (PCM) or the engine control unit (ECU).
What does the coolant temperature sensor tell the ECM?
The engine coolant temperature sensor simply tells the car’s computer (ECM) the current temperature of the vehicle. When the temperature of the coolant reaches between 75 and 95 degrees (depending on the manufacturer specifications), the ECM instructs the radiator fan to turn on and start cooling down the liquid.
How does the ECM know the location of the crankshaft?
It is responsible for telling the ECM the exact location of the crankshaft as well as the RPM (rotations per minute) of the engine. With this information the ECM knows the position of each piston in each cylinder. Using the cam sensor readings, as well as the crank sensor readings, the ECM knows exactly which injector needs to be activated.
