|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.
