Question

have replaced the purge canister and evap solenoid

Answer 1

HI there,

This code can be caused by other parts in the system that could be leaking. The next step here is to perform a smoke test to see where the system is leaking. If it's not leaking and the pressure sensor is good, then you have an electrical issue from the pcm to the vent control valve.
