2003 Ford Mustang, ECM/Inputs/Outputs Waveform
Posted to the Waveform Library on 3/8/2013

This is the VSS circuit being tested close to the ecm. I'm using puncture leads on the both wires with everything connected. Vehicle is at a stand still and cold. Speedo is jumping up and down to about 15 mph.
