Fuel Level Sensor
1) 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 reference values are not indicated, the sensor is faulty.

103 to 117 Ω
Coolant Temperature Sensor
1) Lead Terminal Voltage
1. Disconnect the lead from the coolant temperature sensor after turning
the main switch off.
2. Turn the main switch on and measure the voltage with a voltmeter
across the lead terminal and the chassis. If the voltage differs from the
battery voltage, the wiring harness fuse or coolant temperature gauge is
faulty.
