Pressure Sensor, EVAP: Dismantling

WARNING: This page is about a different car, the 2003 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: A variant of the ORVR is available on the EU market that lacks both shut-off valve and tank pressure sensor (stripped ORVR)
  1. Drain the fuel from the tank.
    IMPORTANT: The tank must never be drained by suction through the filler pipe as this will damage the non-return valve!
  2. Raise the car, making sure that the right-hand lift arm is situated as far to the right as possible so as not to be an obstruction during removal.
