Help with P0502 and P0340...Anders ??? (Kinda long)

The Patient; 1999 9-3 SE Auto with 178000 KM. Two nights ago the ABS warning lights came on and the speedo died. The car then started stumbling at idle (only in gear, only occasionally) Today the check engine light came on.
I just plugged in my trouble code reader and got P0502 (vehicle speed sensor circuit low input) As a Mercury/Mercruiser tech, to me this means low resistance or voltage from that sensor. Is there a way I can check the sensor, or is it time to send the ABS module in for rebuild.
The other is P0340 pending. I installed new plugs about 2 months ago, but havent checked them- from research on the site I'm thinking it's time for a new DIC???
Any help would be greatly appreciated, in a few days I fly across country to bring home a new to me 2003 Aero wagon, (i think the 9-3 may be seeking attention) and I don't want to leave my wife stuck somewhere.
