I only seam to get this code when the temperature is below 15 degrees. I have already replaced the gas cap. I am still trying to locate the fuel tank presure sensor to check the wires. Any other thoughts.
Thanks Dave

fuel tank pressure sensor is in the evap line in the frame rail if I remember right. Are you having trouble filling the tank? your issue may be due to the tank vent icing up.

No problem filling I just keep getting this code when it gets below 15 I want to check the wiring to the sensor before I replace it. Can I get to it without dropping the tank?

Its better to lift the bed up in the front or slide it back to expose the top of the fuel tank, if you are doing it at home

If you have a lift and transmission jack then you can drop the gas tank down, its very very hard to access the fuel line fittings and electrical connections when dropping the gas tank down, and even harder to re-connect them when putting tank back in, and then re-aligning the straps


Bed has 8 bolts in 2011, T55 bolts
And 3 screws to hold Filler
And an electrical plug in for tail lights, drivers side rear
And it can be moved back by 2 people, its not heavy just awkward

With bed off its also easier to test wires and visually inspect EVAP hoses. as these are located behind the gas tank
