another code again.

[20gst]

Ok now I got another code that poped up last night.

Code; P0450
Evaporative emission system pressure sensor/switch.

What caused this thing to come on, ????

 

[NOSNUSE]

check the canister connections and see if there my be a loose line, it could just have a loose connection somewhere.

 

[ss94s10]

the [p0450] light comes on due to a fuel tank differenitial sensor failed
or a fuel vent valve or fuel vapor line blocked

fuel tank differenitial sensor is on top of the fuel pump im not for sure but i think you can only get it when you buy a new fuel pump
but i would have a mechcanic do some diag frist because a new fuel pump is about 277 buck and about 1.5 hours labor


later

Yes, maybe thats why my fuel tank is full of pressure lately and wont let me fill up normally. I just cant find the blockage Ill pull the pump tomorro night if I have time after work. I put in a 255 walboro about 6 months ago. I still hear it good.
Thanks for helping me That sounds like it could be it. cuz everything else is good that I can see.
