Sensors Egr Valve Position For Bentley Azure T. EGR Pintle Position Sensor Describes the operation of the EGR pintle position sensor. The EGR valve position sensor is commonly part of the EGR valve.
A bad EGR pressure feedback sensor means the ECU may not open and close the EGR valve at the right times. The EGR pressure feedback sensor, also known as the delta pressure feedback sensor, is a sensor that detects the pressure changes in the EGR system. This component installs right on top of the EGR valve itself.
Check for a stuck-open EGR valve, an electrical short in a related.
The signal from the DC motor and position sensor are shown and can be downloaded.
Check the EGR valve, hose or electrical connections, as necessary. As a result, is failure may require replacement of the EGR valve. Lab scope measurement of an EGR valve position DC motor and position sensor on an engine under various conditions.
