My check engine light keeps coming on, displays as the evap code p0442.  I’ve changed the canister purge solenoid two times. Both times the light goes off for 1-2 weeks then goes back on. Sensor is tight, all wires connected.  
Any others have this issue? Stuck and don’t feel like dropping wasted money having a mechanic diagnosis.  Thanks.

A guy once told me it's the tank pressure sensor. It can be seen between the cab and bed. I got one. Just never got around to making the swap.
