Hi,

I could not find an existing thread/post on this topic but maybe there already is one that I can access on this topic? If so apologies for the additional post - and if addressed elsewhere and someone could provide a link I would appreciate it. I recently got a 2005 XC90 2.5T AWD. I have been getting 2 OBD error codes that are triggering CEL light. These 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,

- Tim
