Temperature Gauge

Check Temperature Sensor Output

1. With power off, disconnect 2 wire connector at the temperature sensor.

2. Make sure the temperature sensor is at room temperature

3. Using a multimeter on the resistance setting check 2 wire connector resistance

going to the temperature sensor.

4. This is the output for the temperature sensor.

100°F to 240°F and 100°F to 280°F

140°F to 320°F

5. If the temperature sensor output is at 1,000Ω or less then start the engine and

check to see if the temperature sensor output increases.

6. Use the temperature sensor output chart to see if the temperature sensor output

matches the temperature of the engine.

7. 140°F to 320°F temperature sensor may need heated using another heat source

because the engine does not heat temperature sensor above 140°F at idling.

8. If multimeter measures an open or a high resistance over 2,300Ω the temperature

sensor could have a problem.

Check Gauge Resistance

1. With power off disconnect the four wire connector from wire harness that goes to

amplifier box

2. Check wires on studs to make sure wire colors match labels on studs.

Green (GN) and Yellow (Y) and Gray (GY) and White (W)

3. Using a multimeter on the resistance setting check gauge resistance.

4. Connect multimeter leads across studs label green (GN) and yellow (Y).

Resistance should measure around 82Ω

5. Connect multimeter leads across studs label gray (GY) and white (W).

Resistance should measure around 75Ω

6. If mutlimeter measures open in either pair the gauge could have a problem.
