2.0L VIN C PCM Connector C4 Pinout - 30-Pin Wire Colors & Functions

This scanned service-manual page (page header 'Engine Controls - 2.0L, 6-107x') shows the back view of Powertrain Control Module (PCM) connector C4 for a 2.0L VIN C powertrain. The connector is described as a 30-pin gray connector C4 with a green terminal secondary lock insert; a diagram illustrates the connector cavity layout with pins 1, 7, 8, 20, 21, and 30 labeled for orientation (illustration numbers 477056 and 477057). Below the diagram is a complete pinout table listing pin numbers C4-1 through C4-30 with their wire colors and circuit functions. Circuits include fuel injector controls #1-#4, four IAC valve coil control circuits, HO2S 1 heater control, EVAP canister vent solenoid, EVAP tank pressure control solenoid (if equipped), EVAP canister purge valve, four EGR valve coil control circuits, 4WD actuator control and 4WD signal, CKP sensor signal high/low, ignition coil #1-#4 controls, VSS signal, CMP sensor signal, ground, DLC ground, and CKP sensor shielded ground (bare wire). A reader can use this page to identify PCM wire colors and functions at connector C4 for diagnostics on the 2.0L engine's fuel, ignition, emissions, and 4WD circuits.
