Code P0188 2000 Ford F150 Description

The P0188 code for a 2000 Ford F150 indicates a problem with the Engine Fuel Temperature Sensor B Circuit registering a high input. The fuel temperature sensor is a crucial component that measures the temperature of the fuel in the fuel tank. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the sensor detects a high input, it means that the fuel temperature is higher than expected, which can lead to various performance issues.

Tech Notes for P0188 2000 Ford F150

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

When is the Code Detected?

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