Fuel Temperature Sensor (FTS)
The fuel temperature sensor is used to detect the fuel tempera-
ture in the injection pump. 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 sensi-
tive to the change in temperature. The electrical resistance of the
thermistor decreases as temperature increases.
The sensor is built into the inside electrical circuit of the injection
pump.
Malfunction is detected when ...Check Items
(Possible Cause)
lAn excessively high or low voltage from the sensor is
detected by ECM.lHarness or connectors
(The sensor circuit is open or shorted.)
