Fuel Tank Pressure Sensor: Testing and Inspection
Inspection
1. Reinstall the fuel pump ground wire to the fuel pump access cover screw. Connect the negative terminal to the battery.
2. Vent the fuel tank by removing the fuel filler cap.
3. Turn the ignition switch to the ON position.
4. Using a voltmeter, measure voltage at all three fuel tank pressure sensor terminals in the fuel tank sending unit connector.
WHT/BLK - 2.0 - 3.0 V (signal return voltage/base reading)
If signal voltage reads 5.0 volts, check the sensor ground wire.
GRN/YEL - 0.0 V (sensor ground)
YEL/GRN - 5.0 V (reference voltage)
