Coolant Temperature Sensor - Mahindra XUV 500 Diagnostic Manual

DIAGNOSTIC MANUAL
P0118 - Signal Range Check for coolant temperature sensor above maximum limit

COOLANT TEMPERATURE SENSOR

The CTS sensor is a variable resistor whose resistance changes as the temperature of the engine coolant
flowing past the sensor changes.(NTC resistor) When the coolant temperature is low, the sensor
resistance is high; when the coolant temperature is high, the sensor resistance is low. The ECU checks CTS
voltage and uses the information to help smoothen the engine operation
