1995 Geo Metro, EGR Control Waveform
Posted to the Waveform Library on 2/9/2005

Control (ECM) side of EGR solenoid was approx 1.3 volts. I moved the black lead of the vantage from ground to battery positive. Does this indicate that the control side is actually grounded and it is not just a poor connection?
