EGR Valve Position Sensor: Description and Operation
The PCM monitors the EGR valve pintle position input to endure that the valve responds properly to commands from the PCM and to detect a
fault if the pintle position sensor and control circuits are open or shorted. If the PCM detects a pintle position signal voltage outside the normal
range of the pintle position sensor, or a signal voltage that is not within a tolerance considered acceptable for proper EGR system operation, the
PCM will set DTC P1406.
