P0180: Engine Fuel Temperature Sensor A Circuit Low Input (Eft)

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

P0180 - ENGINE FUEL TEMPERATURE SENSOR A CIRCUIT LOW INPUT (EFT)

Description:	The comprehensive component monitor (CCM) monitors the EFT sensor circuit to the PCM for low and high voltage. If voltage falls below or exceeds a calibrated limit and amount of time during testing, the test fails.
Possible Causes:	Open or short in the harness. Low ambient temperature operation. Improper harness connection. Damaged EFT sensor. Damaged PCM.
Diagnostic Aids:	Verify the EFT-PID value to determine an open or short.
