As mentioned, got a P0452 code in the wifes 04 Dodge Durango.

It looks to be related to the pressure sensor that vents fumes to the evap. emission system (vapor canistor).

Just wondering what the experienced dealer mechanics have encountered with this other than the obvious conclusion that the sensor is bad?? It appears to be part-of-assembly to the fuel sending/pump unit in the tank.

The sensor isn't available separately from what AZ tells me.

Any info is appreciated.
