COOLANT TEMPERATURE SENSOR XII. A semiconductor material changes its resistance when exposed to variable temperature source. There is one temperature sensor fitted on water box. Resistance decreases as temperature increases this provides engine operating temperature input to the ECU. Corrections for injection parameters are done by the ECU based on coolant temperature to run the engine with maximum efficiency at all temperatures. SENSOR LOCATION CONNECTOR DETAILS PINOUT DETAILS Equipment Required 3 ½ Digital Multi-meter (DMM) • Water Bath • Heating arrangement for boiling the water • Measurement Set-up showing the water level up to which the sensor should be dipped. PIN NO DESCRIPTION 1 Sensor Signal 2 Sensor Return Diesel Engine Ph-2 (CAFÉ) 207
