1996 Ford Explorer, EGR Control, EVP Scandata
Posted to the Waveform Library on 3/2/2003

Right in the middle (the green line is where the MIL came on) PO402 (excessive EGR flow) I believe we have 2 problems. It seems we have to high of a voltage and the ECM believes we have EGR at idle and it appears at times it does not work at all.
