Code P0180 1999 Ford F150 Description

The P0180 diagnostic trouble code (DTC) for a 1999 Ford F150 indicates that there is a low input signal from the Engine Fuel Temperature Sensor A circuit. This sensor is responsible for measuring the temperature of the fuel in the engine. The Engine Fuel Temperature Sensor A is a crucial component of the fuel system, as it provides important data to the engine control module (ECM) to ensure the optimal air-fuel mixture for combustion. When the sensor detects a low input signal, it means that the fuel temperature is below the expected range, which can lead to various performance issues in the vehicle.

Tech Notes for P0180 1999 Ford F150

The comprehensive component monitor (CCM) monitors the EFT sensor circuit to the PCM for low and high voltage. If voltage were to fall below or exceed a calibrated limit and amount of time during testing, the test will fail.

When is the Code Detected?

An excessively high or low voltage is sent to Powertrain Control Module (PCM) by the Engine Fuel Temperature (EFT) Sensor.
