P0180 – Fuel Temperature Sensor A Circuit
Description:                 The comprehensive component monitor (CCM) monitors the fuel temperature sensor circuit to the powertrain control module (PCM) for low and high voltage. The test fails if the voltage falls below or exceeds a calibrated limit and amount of time during testing.
Possible Causes:       
 
Open or short in the harness
Low ambient temperature operation
 
Incorrect harness connection
 
Damaged fuel temperature sensor
Diagnostic Aids:          Verify the FRT parameter identification (PID) value to determine an open or short.
