Where is the fuel tank pressure sensor?

Does anyone know where the fuel tank pressure sensor is located on a 2002 Sport Trac (plastic gas tank). Is it incorporated into the fuel sending unit or an evaporate canister line or something?

I have a P0453 code (Evaporative Emissions Control System Pressure Sensor High Input) that I’m trying to track down. I spent about 30mim yesterday looking for it on the tank with no luck, but it’s kinda hard to inspect the top of the tank without dropping it.

Never mind. I went out and looked for it again with fresh eyes and found it. It’s not on the fuel tank like the earlier models. It’s mounted between the tank and the canister inline with an emissions hose. Looks like the previous owner forgot to hook it back up after dropping the tank to change the fuel pump.

I would check to make sure the tank purger valve is working as well before I go changing the pressure sensor.

I probably will if the code comes back, but at this point I don’t think the sensor is bad. It’s just been unplugged since I bought it.

Unplugged sensor = P0453
