EGR Closed Valve Pintle Position
Scan tool displays
0.0-5.0 volts. Represents the learned voltage that the
PCM uses to determine whether or not the
EGR valve is fully closed and is at
0 percent pintle position. If the Desired
EGR Position is
0 percent and a difference of more than
0.4 volt between EGR Feedback and EGR Closed Valve Pintle Position is detected, DTC P1406 will set.
