Fuel Temperature Sensor: Description and Operation
Fuel Temperature Sensor (Only Vehicles With Demand Controlled Fuel Pumps)
The fuel pressure sensor is combined and consisted of both the fuel pressure sensor and the fuel temperature sensor. The sensor detects the fuel pressure
(the absolute pressure) and the temperature of the fuel in the fuel rail.
Fuel temperature sensor
The temperature sensor is an NTC sensor. The sensor is supplied with voltage (signal) from and grounded in the engine control module (ECM).
The signal to the engine control module (ECM) varies depending on the fuel temperature. The resistance in the sensor changes with temperature. Low
temperature results in high voltage (high resistance). High temperature results in low voltage (low resistance).
The engine control module (ECM) uses the signal to calculate the volume of the fuel.
The fuel pressure sensor is on the left-hand end of the fuel rail.
