|P0183 – Fuel Temperature Sensor A Circuit High|
|Description: The comprehensive component monitor (CCM) monitors the fuel temperature sensor circuit to the powertrain control module (PCM) for high voltage. The test fails if the voltage exceeds a calibrated limit for a calibrated amount of time during testing.
Possible Causes: • Open circuit
• Open or short to voltage in the harness
• Incorrect harness connection
• Damaged fuel temperature sensor
Diagnostic Aids: Verify the FRT parameter identification (PID) value to determine an open or short.
