Need code interpretation!!

OK, I did the search and found the explanation of the code. Wanted to get some thoughts on these results:

Advance Auto Parts

Vehicle Scanned
Global OBDII
Vehicle

P0453
EVAP Emission
Control System
Pres Sensor High

DTC Pending (Codes)

No Faults Detected.

So I did a search here for the P0453. It's "Fuel tank pressure signal circuit input above maximum". What the heck is that?

Thanks for any help!!!

Mike

Basically means a damaged Fuel Tank Pressure (FTP) sensor or a short somewhere in the circuit.

Could it be as simple as replacing the old gas cap with a new one? I'm sure the one on there is original. It was a suggestion by someone else. Thoughts?

Very doubtful. I never leave it running when fueling. I top it off, but I don't know that I've over filled it.
Where would this pressure sensor be located? I can't seem to find any more information on it.
Thanks for the help!

The FTP sensor is located on the top of the fuel tank, perhaps part of the pump module assy, perhaps a separate sensor.

I haven't dropped the tank on my F150, but on my Contour, it's a separate sensor.

The PCED has a diagnostic procedure for loaciting the fault, requires a scan tool that can read PIDs.
