Engine Control Module (ECM)
WARNING: This page is about a different variant/trim than selected.
The ECM controls all of the ignition system functions, and constantly corrects the spark timing. The ECM monitors information from various sensor inputs that include the following:
- Throttle position (TP) sensor
- Engine coolant temperature (ECT) sensor
- Mass air flow (MAF) sensor
- Intake air temperature (IAT) sensor
- Vehicle speed sensor (VSS)
- Engine knock sensor (KS)
- Manifold absolute pressure (MAP) sensor
- Intake air pressure and temperature sensor
