1991 Honda Accord, EGR Control Waveform
Posted to the Waveform Library on 10/19/2007

At this point I am also checking EGR control signal at the ECM (green) and at the EGR solenoid (yellow). I was hoping that it was just a bad connection, but this waveform confirms there is no EGR signal from the ECM.
