Ok. I have a 2006 Ody EX-L w/ Nav and RES. I am getting an engine light code of P0451 and P1454 - Evaporative Emission Control System Pressure Sensor Range/Performance and Fuel Tank Pressure Sensor.

I cannot find any information regarding where the FTP sensor is located (except possibly above the gas tank, but I still cannot eye it). Does anyone know where else I can look to find this and troubleshoot?

Thanks in advance.

Just wanted to add - I replaced the gas cap twice already. The code has been there for 3 months or so.

I went to the garage to grap my manual, so I could tell you. When I went out there, my lights were flashing on and off. I think I may have a relay problem. Regardless, I found the location. Its underneath, but closer to the drivers footwell (on the outside next to the evap canister. If you PM me your email, I'll email you pics.

Ok. Thanks to mwmcginn I was able to locate and replace this sensor. It was infact defective and apparently there is a part bulletin regarding this ftp sensor. Anyways, if you are looking for it: It is located under the driver's seat under the car. You have to remove the cover plate (or shroud) with 4 or 5 screws to access the whole evap bundle. I think the "canister" and other parts related to it are contained in this bundle. This bundle needs to be removed as well with again 4 or 5 screws (btw they are 10mm socket screws). The FTP sensor is on the top of that whole bundle. It reads "Sensor, vent pressure". Remove the grey plastic lock clip and small tube and pull really hard to release it from the seated located. Its kind of hard because of the oring. I paid $90 after tax at the Honda dealership because O'reilly and Autozone do not carry this part yet. Easy fix and only took about 20 min - ofcourse after a few hours of looking for it until mwmcginn helped me out. Thanks mwmcginn. Way to come through!:)

Do you only smell the gas only if you fill the tank to the full or is it all the time? I will try to post a link to a diagram.

yes i smell gass when i fill up and when i get home when the car is off i went to honda and they want 120. for a diagnose the problem but my friend that work for another dealer shop told me if i dont have pressure when i open the gas tank it could be the gas tank pressure sensor

You could use a spray bottle with soapy water to find the leak. You can buy the item aftermarket, but be sure you are getting a high quality product. Have you tried to smell where it is coming from or the soapy water technique. Let me know. When filling up the tank does the gas go in normally? Or does it take forever to fill up the gas tank? When you smell gas go underneath with a flash-light see if you can spot wet gas underneath. Let me know.

Forgot to mention be sure that you have the gas cap fully closed & the tank to build pressure before spraying with soapy water. Also check for broken clamps or rusted ones. Check for anything unusual on the fuel tank. Let me know.
