5 VOLT SUPPLIES
Primary 5-volt supply:
-
supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
-
supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
-
supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
-
supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply:
-
supplies the required 5 volt power source to the oil pressure sensor.
-
supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
-
supplies the 5 volt power source to the transmission pressure sensor (if equipped with an RE automatic transmission).
IGNITION CIRCUIT SENSE
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the RUN or START position. This is referred to as the
"ignition sense" circuit and is used to "wake up" the PCM.
