ECM Components

The ECM is designed to maintain exhaust emission levels to government mandated standards while providing excellent driveability and fuel efficiency. The ECM monitors numerous engine and vehicle functions via electronic sensors such as the throttle position (TP) sensor, heated oxygen sensor (HO2S), and vehicle speed sensor (VSS). The ECM also controls certain engine operations through the following:

• Fuel injector control
• Ignition control module
• Valve timing control
• Throttle valve control Cruise control
• Evaporative emission (EVAP) purge
• A/C clutch control
