Fuel System 128 Diesel Control System
Fuel Temperature Sensor (FTS)
Function And Operation Principle
The Fuel Temperature Sensor (FTS) is installed on the high pressure fuel pump and measures the temperature of
the fuel supplied from the fuel tank (via fuel filter). The FTS uses a thermistor which resistance is in inverse
proportion to the temperature (NTC: Negative Temperature Coefficient). With this signal, the ECM can
adjust the injection amount.
At high temperature, vapor-lock in fuel line or oil membrane destruction may appear. Especially oil membrane
destruction deteriorates fuel's lubrication performance and it may damage the high pressure fuel pump and the
injector.
