I have a check engine light on. I read the codes and am getting 455...the reader says emissions system leak (large), but thought I would check on the board first...anybody have this before? I have a new air pump, check valve and both O2 sensors. Car has 117K on it. thanks.

Gas cap is the first item to check.
Make sure you don't pump gas with the ignition key ON.
After that, clean the EVAP purge valve, mounted on the radiator fan shroud.
Make sure all the hoses are attached where they belong.
Most of the time, replacing the EVAP purge valve solves the problem.
I cleaned the one on my 98 V70 about 2 yrs ago and the problem did not return.

Does anyone have the part number of the 1998 S70 purge valve or a picture of it?
