Fuel Tank Pressure Sensor: Removal

The fuel tank pressure sensor is located on the top of the fuel tank near the rear of the tank.

1. Remove fuel filler pipe and fuel tank from vehicle. Refer to FUEL TANK .
   NOTE: Use care when removing tank pressure sensor from fuel tank. The mounting pad is part of the tank and if damaged will require replacement of the tank.
2. Unlatch the retaining arm over the tank pressure sensor (use small, flat blade screwdriver).
   NOTE: Avoid contact of any tool with the top surface of the fuel tank pressure sensor. If this surface is damaged, the sensor will require replacement.
3. Disengage sensor from the locating uprights at the connector-end using hand pressure and fingertips only.
4. Remove tank pressure sensor from its mounting boss on the fuel tank using a flat blade screwdriver at the rear of sensor to pry up and assist in removal.
