Electronic Control System

The electronic control system monitors engine operating conditions, processes the information, and controls the engine for optimum performance and minimum emissions.

Input signals are generated by the Engine Coolant Temperature (ECT) sensor, Manifold Air Temperature (MAT) sensor (1.8L turbo only), Manifold Absolute Pressure (MAP) sensor (1.8L turbo only), Mass Air Flow (MAF) sensor (3.8L V6 only), Exhaust Oxygen (O2) sensor, Throttle Position (TPS) sensor, Park/Neutral (P/N) switch, and Vehicle Speed sensor (VSS).

The ECM also receives signals from the starter solenoid (1.8L 4-cylinder models during cranking mode only), the air conditioner selector switch, and the ignition distributor.
