2005 XC90 2.5T P2401/P2419 eval system leak, signal low
Hi,
Starting a new thread for this topic based on feedback recd yesterday. I recently got a 2005 XC90 2.5T AWD and am starting to tune it up and right some of the wrongs that have been done to it by the prior owner(s). I see 4 error codes via my iCarsoft VOLII tester - but it appears that it is the same error message repeated twice? These 2 OBD error codes that are triggering CEL. I cleared them and they went away - only to come back a few day s later. The codes are:
P2401 Volvo evaporative emission system leak detection pump control circuit low
P2401 -- ECM-433D -- Leakage diagnostic unit, pump -- Signal too low
-and-
P2419 Volvo evaporative emission system switching valve control circuit low
P2419 -- ECM-432D -- Leak diagnostic unit, valve -- Signal too low
Does anyone have any debug/repair suggestions for these? Appreciate it!
Thanks,

sounds like the connector or wiring to the purge valve and pump may be creating an open circuit. You can check volvowiringdiagrams.com to see which relay/junctions/wires are in play to do some continuity testing. The purge valve is cheap enough to replace ($30-40), the pump is not so you'd want to get this properly diagnosed before dropping in parts...
