EGR Learned Minimum Position
The scan tool displays
0-5 volts. This represents the learned voltage that the PCM uses to determine whether or not the
EGR valve is fully closed, and 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.
