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.
