How To Diagnose P0451 | Fuel Tank Pressure Sensor

[@EbonyOak11]

so is the fuel tank pressure on the actual tank itself or is it outside connecting other things?

[@autorepairprocedures]

Fuel pressure sensor is usually on the fuel tank. On some makes and models can be access the fuel pressure at fuel access door. But most of the time fuel tank has to drop of the fuel tank to access this sensor.
