ok so what is the differance between a fuel tank pressure sensor and a fuel pressure regulator.. i know that the regulator regulates the amount fuel being sent to the motor but what is the sensor for... and does any one know where the sensor is located on a 99 accord and how hard will it be to replace it

My first question is going to be what code you got that said the sensor was bad or why you think that's the issue? Are you sure it wasn't just a loose gas cap that threw the code?

i pulled a P1457 i already had the car checked out and every thing passed and the only two options that remain are.. the sensor is malfunctioning or the PCM is malfuctioning.. so i just want to see where the sensor is located and how hard it would be to replace it.. i know they run about 100 bucks so if i can replace it myself theres no labor charge.

It's on the top of the gas tank. The Helm book says you gotta drop the tank to get at that sensor.
Nasty, I've been in his other thread where the rest of the story is laid out...

When mine threw P1457, it was a valve that I could remove. I didn't have to remove the canister out of the car. That looks like it would be a chore, with not really a lot of room to get your tools or fingers in to work.

I just went through this process on my '98. It is pretty easy to get the canister out, which you will likely need to do just to get to it. There is a black plastic housing that covers the 2-way valve and the pressure sensor (if it is indeed #36 on diagram). This took me about 15 minutes to get in and get out. There is one 12mm bolt holding the canister in. With a 6in extension you can easily remove it. Remove the vapor line attached to the canister before letting it drop, you really don't want to break that one :-)!!! Open the protective housing located between the canister and the vapor filter, then remove the two way valve/sensor assy. It's a cake walk. Tools needed: Philips head #2, 6in extension, ratchet, 12mm socket, and angled long neck needlenose (for clips and vapor line (squeeze sides and it will pop right off).
Good Luck!!!

OH YEAH>>>
You will need to take the canister mounting bracket off of the car also to access the bolt holding the sensor in (12 or 10mm socket). When it gives you trouble pulling it out, turn it 45 degrees to the left, then push it toward the front of the car, and pull the rear portion out first. You will have to free a few lines to do this...
