I replaced the filter,pulled battery cable to clear codes, and light stayed off for a day but now back on. My question is where is the tank, as it says possible cause for light on is corroded wire on tank. Im assuming there is some sort of pressure switch, and am hoping it is corroded. Does anyone know where it is located. Any help will be greatly appreciated, Thanks,

I would look at the emissions system for problems. Vapours are kept in a closed system, maybe the pressure in that system is too high.
From the shop manual.


The evaporation control system prevents the emission of fuel tank vapors into the atmosphere. When fuel evaporates
in the fuel tank, the vapors pass through vent hoses or tubes to an activated carbon filled evaporative canister.
The canister temporarily holds the vapors. The Powertrain Control Module (PCM) allows intake manifold vacuum to
draw vapors into the combustion chambers during certain operating conditions.
This vehicle uses a pulse-width modulated purge solenoid system. The PCM controls vapor flow by operating the
purge solenoid. Refer to EVAP Purge Solenoid in this section.



See section 25 page 15
