Five volt sensor supplies-primary and secondary

DESCRIPTION

Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and secondary.

OPERATION

These 2 circuits will:

  • supply the required 5 volt power source to the Crankshaft Position (CKP) sensor.
  • supply the required 5 volt power source to the Camshaft Position (CMP) sensor.
  • supply a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
  • supply a reference voltage for the Throttle Position Sensor (TPS) sensor.
  • supply the required 5 volt power source to the oil pressure sensor.
  • supply the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
  • supply the 5 volt power source to the transmission pressure sensor (if equipped with an RE automatic transmission).

Fuel level sensor-pcm input

DESCRIPTION

The fuel level sensor (fuel gauge sending unit) is located on the fuel pump module.

OPERATION

Refer to Fuel Gauge Sending Unit in the Fuel Delivery section for information.
