MFI Control Relay

WARNING: This page is about a different car, the 1996 Mitsubishi Pickup, 1996 Mitsubishi Galant, 1996 Mitsubishi Eclipse, and 1996 Eagle Summit Wagon. However, it is still accessible from the selected car via links, so may be relevant.

Multipurpose relay switches power to vehicle sensors and actuators including Volume Airflow (VAF) sensor, crankshaft position sensor, idle speed control, injectors and fuel pump. When ignition switch is turned to ON position, PCM energizes coils controlling injectors, VAF sensor and idle air control. When ignition switch is turned to START position, PCM energizes coils (through park/neutral position switch on A/T models) to supply power to fuel pump. Relay failure will cause a no-start condition. For testing procedure, see SYSTEM/COMPONENT TESTS - 2.4L 4-CYL article.
