p0452-evap pressure switch stuck closed

[papacam1226]

Excuse my ignorance I'm new to all this got my first ram as a gift from my father in law. A 2014 limited with nearly 200,000 miles lol. Had a significant timing issue which lead me to my first ever engine rebuild. Timing tensioner and guide where blown replaced the whole timing system including mds delete got everything back together truck is running decent with a bit of a rough idle. getting an evap code p0452" pressure switch stuck closed". Is this just a purge valve issue or something deeper anyone have any experience with this issue?

Thanks in advanced

Got the same stupid error, along with a P0441.

Alfa says the ESIM on the back of the gas tank is seized. Again.

Mechanic says it's likely either mice eating the wires, or the sensor needs a wack.

We don't have mice in my area, and I tried wacking both sensors.

The EVAP system is a load of ******** mandated by the morons in EEEEEPA.

And we are just stuck with it causing our engines to have issues.
