2.Fuel Control Operation

3) Oxygen sensor mounted in the exhaust manifold. This sensor produces a voltage, based on the oxygen content of the exhaust stream, to indicate the current

A/F. 4) Engine temperature to indicate the fuel requirements for cold starting, general operation, and as a monitor of proper engine functional condition.

Note: These parameters can be monitored during engine operation using the diagnostic tools, as described in the troubleshooting section.

INPUT (To ECU) OUTPUT (From ECU)

MAP (Manifold Absolute Pressure) FCSV (Fuel Control Solenoid Valve) RPM (Engine RPM) OXY (Oxygen Sensor Voltage) ET (Engine Block Temperature)

Note: See Wiring Schematic section for wiring locations and wire colors.
