(1) Checking
Fuel Level Sensor Continuity
1. Remove the fuel level sensor from the fuel tank.
2. Measure the resistance with an ohmmeter across the sensor
terminal and its body.
3. If the measurement are not indicated, the sensor is faulty.
W1022582
Coolant Temperature Sensor Continuity
1. Measure the resistance with an ohmmeter across the sensor
terminal and the chassis.
2. If the measurement is not indicated, the sensor is faulty.
W1022725
Fuel Gauge and Coolant Temperature Gauge Continuity
1. Remove the panel board from the tractor.
2. Check the continuity with an ohmmeter across the FU terminal
(2) and IG terminal (3) and across the FU terminal (2) and GND
terminal (4).
3. If infinity is indicated, the fuel gauge is faulty.
4. Check the continuity with an ohmmeter across the TU terminal
(1) and IG terminal (3) and across the TU terminal (1) and GND
terminal (4).
5. If infinity is indicated, the coolant temperature gauge is faulty.
