P0453 - Evaporative Emissions Control System Pressure Sensor High Input
I cant seem to get rid of this code.
Things I tried.
Replaced fuel cap - no good
Replaced ftp sensor on evap canister - no good
Replaced evap purge valve - no good
Dont know what to do next. Already wasted 150$ on parts with no luck. Once I clear the code, it comes right back as soon as the car is started.

A P0453 code may be caused by one or more of the following:
- Open on FTP sensor signal wire
- Short to voltage on FTP sensor signal wire
- Bad FTP sensor
- Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank
- Loose/damaged FTP sensor connector
- Loss of ground to the sensor

Possible Solution
I got this same code on my 03 RSX Type s. I replaced the evap canister and the purge valve. I think it may be that the actual wires in the connector become damaged. Talking about the orange plug/connector that plugs into the evap canister. Will see what I can find.

Any Update in this Thread?
I am getting the same P0453 code on my 2007 RDX along with P2422, Replaced the FTP Sensor (yellow Circle), Purge valve is open (red Arrow), can plow air thru canister. I Haven't replaced the Fuel cap yet.
