There wont be any power going to the wheel spd sensors. A wheel speed sensor generates its own AC voltage. If you wanted to test them, there are two wires on the connector, use a DVOM set on AC voltage, and touch both wires, then spin the wheel and see if you get a voltage reading. The reading should go higher the faster you spin the wheel. However, the abs and trac off lamp may be on b/c of a wiring issue from the sensor to the Electronic Brake Control Module (EBCM). Best bet, get the code read from a dealer or someone with a Tech 2, and that will tell you which wheel speed sensor circuit is the issue.

Sorry so long, but hope it helps.
