Trouble Shooting Steps
Pressure Gauge
Check Pressure Sensor Output
1. With power off, disconnect 2 wire connector at the pressure sensor.
2. Using a multimeter on the resistance setting check 2 wire connector resistance
going to the pressure sensor.
3. This is the output for the pressure sensor.
4. If the pressure sensor output is at 7 or more then start the engine and check to
see if the pressure sensor output change.
5. Use the pressure sensor output chart to see if the pressure sensor output matches
the pressure of the engine.
6. If multimeter measures an open or a high resistance over 114 the pressure
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 86
5. Connect multimeter leads across studs label gray (GY) and white (W).
Resistance should measure around 78
6. If mutlimeter measures open in either pair the gauge could have a problem.
Check Amplifier Box
1. With power off disconnect 2 wire connector at the pressure sensor.
2. Make sure the four wire connector going to the gauge is connected.
3. Turn power to gauge on.
4. Using a multimeter on the voltage setting check voltage at the gauge.
Green(+)/Yellow(-) Temperature Sensor Output Gray(+)/White(-)
2.1 Volts Open -1.7 Volts
# 2.1 Volts 10 PSI -1.3 Volts
# 2.1 Volts 20 PSI 0.6 Volts
# -1.9 Volts 60 PSI 1.5 Volts
# Connect pressure sensor for these measurements.
