- Repair damaged wiring to the fuel tank pressure sensor.
Where is the EVAP pressure switch located?
The EVAP Pressure Sensor, also known as a Fuel Tank Pressure (FTP) Sensor is a device that measures air pressure or vacuum in the evaporative emission (EVAP) system. This sensor is typically found on top of or inside of the fuel tank.
Where is the FTP sensor located?
fuel tank
It is located on top of the fuel tank, it is actually part of the fuel pump/fuel gauge sending unit module, however it can be purchased alone.
What is the code P0452?
