How the DPFE Sensor Operates Within the EGR System The operation of the DPFE sensor is intricately linked to the EGR valve and the engine's vacuum system. Diagnosing and Replacing the DPFE Sensor Diagnosing a faulty DPFE sensor usually requires a scan tool to view live data streams and compare the expected pressure differential against actual readings.

This process lowers combustion temperatures, which is the primary method for reducing NOx emissions. This diaphragm flexes in response to the pressure difference, moving a potentiometer that changes the resistance value sent back to the ECU.
Performance issues such as rough idling, engine hesitation during acceleration, or even stalling can occur if the sensor provides incorrect data. Common Symptoms of a Failing DPFE Sensor When a DPFE sensor begins to fail, it often triggers the check engine light and stores diagnostic trouble codes, typically related to EGR flow insufficient or system malfunction.

When the ECU commands the EGR valve to open, the resulting pressure change flows through these ports to the sensor's diaphragm. Drivers may notice a noticeable decline in fuel economy as the engine struggles to maintain the correct air-to-fuel ratio.
