EGR Closed Valve Pintle Position

Scan Tool Range 0.0 to 5.0 volts. This represents the learned voltage that the PCM uses in order 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 the EGR Feedback and the EGR Closed Valve Pintle Position is detected, DTC P0405 will set.
