P0453 Ford Code - EVAP Pressure Sensor/Switch High
Quick Answer
The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. Common causes include Faulty Evaporative Emission System (EVAP) Pressure sensor, Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted, Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Start by checking the connectors to the fuel pump. What model and year is your Ford?
-
Got this code 3 days before my 05 Expedition died. Turns out the wiring harness under the drivers side frame was disconnected and slowly worked its way loose. People thought thousands of dollars in repair, but it was really a loose wire.

Just changed fuel sender unit on 2001 Grand Marqius using same fuel pump and check engine light came on Wasnt on before Code PO453
-
The P0453 code is for the EVAP system pressure sensor. The sensor is inside the fuel tank. You may have left something disconnected or did not closed properly the fuel tank.
-
I checked the old sender unit and there wasnt a sensor On the outside right top of the fuel tank there was a sensor with a plug that came out of the sender unit Β Wondering if this is evap sensor
-
More than like that is that was the connector for the EVAP pressure sensor

I have a 2005 ford expedition and took my car into the dealer for spark plug change. When i got it back they told me i needed a fuel tank pressure sensor and was charging me $850. thins is when i reset it with the obd2 scanner it picks it up right away without having to drive it. this tells me its disconnected since it doesnt even take a few driving cycles to make the CEL come on. It turns on right when i start the car even after resetting it.

Not necessarily. If the sensor failed (internal damage) it will also trigger the code right away or you wont be able to clear the code.

Where is the Evap Pressure Sensor/Switch to a 2010 Ford Escape XLT 3.0L - V6 - FWD -SUV ? Can it be changed in this vehicle?
-
For your vehicle, the P0453 code is the Fuel Tank Pressure (FTP) sensor. The sensor is on top of the fuel tank. You should be able to access the FTP sensor through the fuel tank access cover under the rear seat. Here is the only image I got, I hope that helps.

The FTP (Fuel Tank Pressure) Sensor it is a tube assembly located on top of the fuel tank.

Can anyone tell me where the sensor is located on a 2012 F250 6.2l?
f. Is there a splice in type system to replace the sensor instead of having to purchase the front to back line Ford sells? -
