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

hope this helps

^yea ive read that list before.

was hoping that someone else had this code before and figured it out

ordered a used evap canister on ebay to see it that cures it.

bump

I'd like to know how this problem was solved, I'm having thesame problem with my TL

Any update on this?

:zombie:

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.
