Ford P0188 OBD-II Trouble Code Definition:
P0188 Engine Fuel Temperature Sensor B Circuit High Input
P0188 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0188
Fuel Temperature Sensor B Circuit High
What does the code mean? OBD-ii Code P0188 definition:
The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
