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)
5. In the engine compartment, disconnect the hose at the evaporative emissions canister coming from the fuel tank.
