• Q: How to remove the Vapor Pressure Sensor on 2009 Toyota Prius?

  A: The Fuel Tank Pressure Sensor removal process begins by uninstalling the rear No. 2 floor board as well as the rear deck floor box and rear No. 3 floor board. Follow battery cable removal of the negative terminal by waiting at least 90 seconds to stop Air Bag and seat belt pretensioner activation. Workers should proceed with removing the lower center instrument panel finish panel followed by the rear seat cushion assembly and then the rear floor service hole cover and front floor panel brace along with the front exhaust pipe before extracting the fuel tank sub-assembly. To proceed with removal pull out the fuel tank pressure sensor from the fuel tank retainer after disconnecting the connector and removing the tube joint clip. A thorough check should eliminate dirt and foreign elements from the fuel tank pressure sensor before commencement of the work while avoiding scratches and foreign objects against both parts due to the O-ring sealing the plug on the sensor. The fuel tank pressure sensor disconnection requires manual work without any tool assistance.
