I'm at VIR this week and my car began throwing the P0453 Evaporation Emission Control System Pressure Sensor High Input code.

I can clear it and it will run fine. But when I turn the car off and then start it again to go on another run, I get the code back.

Any ideas on how to fix it other than clearing it every time?

Also, any ideas RE why it would start at the track?

Thanks in advance...

I think all that evap stuff is in the rear under the spare tire. Maybe you banged it up

Fords sometimes have an issue with overfilling, it soaks the evap material but it should dry up after a while, not sure if this is the problem just throwing in an idea

Thanks for the replies. Didn't bang it up at all, and it's still throwing the code. Car ran great the whole time, though, so I guess will have to investigate further.

Any other ideas will be appreciated.

This page sounds like something could be disconnected?
