Output Signals

NOTE: For theory and operation on each output component, refer to the system indicated in brackets after component.

The ECM processes information from the input sensors and sends appropriate voltage control signals to the following engine controls:

A/C Compressor Clutch (Idle Control)
Engine Cooling Fan (Miscellaneous ECM Controlled Signals)
Evaporative Emission Control System (Emission Systems)
Fuel Injector Solenoid (Fuel Control)
Fuel Pressure Regulator (Fuel Delivery)
Fuel Pump (Fuel Delivery)
Fuel Pump Relay (Fuel Delivery)
High Energy Ignition (Ignition System)
Electronic Spark Timing (Ignition System)
Idle Air Control Valve (Idle Control)
Torque Converter Clutch Solenoid (Transmission Controls)
Transmission Shift Light (Transmission Controls)
