Coolant Temperature Sensor
The coolant temperature sensor is connected to the engine coolant system near the water pump. It uses
coolant temperature to present a variable resistance to the ECU. Test the coolant temperature sensor if the
controller records Alarm Code 18 or 41 and the coolant temperature appears to be normal.

Sensor Test
1. Turn the unit On/Off switch to the “OFF” position.
2. Disconnect the sensor at the plug next to the sensor.
3. Turn the unit On/Off switch “ON”.
NOTE: Polarity must be considered when connecting temperature sensors. If a sensor is connected
backwards, the display will show a reading below -40 C (-40 F) or above 130 C (266 F) and record
Alarm Code 101. Consult the unit wiring diagram or schematic for correct connections.
4. Enter the Engine submenu of the Data Menu and scroll to the engine temperature screen. If the display
shows a reading below -40 C (-40 F) or above 130 C (266 F) check the sensor wiring, the sensor
polarity.
