EGR Signal
The SCAN tool monitors only the ECM drive command to the
EGR solenoid. On models with Pulse Width Modulated
EGR, reading is duty cycle of ECM signal from 0-100 percent. On models with EGR solenoid, "on" or "off" status of
solenoid is indicated. Normal reading with engine running at idle should be 0 or off.
