You have restriction in the exhaust somewhere and it's causing it to backflow.

What is DPFE sensor?

Dpfe sensor is the delta (differential) pressure feedback egr (exhaust gas recirculation) it monitors the pressure on the egr valve to make sure it is working.


What does the differential pressure feedback exhaust sensor do?

This sensor varifies flow of the exhaust gases to the intake manifold. If flow is interupted the sensor will inform the onboard computer that the exhaust recirculation system has failed resulting in a check engine light to come on.


What is EGR sensor?

exhaust recirculation valve, helps with your emissions


What do the Error codes 0405 and 0404 mean?

Code 0404 is the exhaust gas recirculation circuit range performance problem. Code 0405 is the exhaust gas recirculation sensor A circuit low.


How do you repair p0401?

The exhaust gas recirculation (EGR) system has insufficient flow. It could be caused by the differential pressure feedback EGR sensor being faulty, there t is a blockage in the EGR tube (most likely from carbon buildup), the EGR valve is bad, or the EGR valve may not be opening.


What is the dpfe sensor on a 2002 Mazda millenia?

The DPFE (Delta Pressure Feedback EGR) sensor on a 2002 Mazda Millenia is an emissions control component that monitors the pressure difference across the EGR (Exhaust Gas Recirculation) system. It helps ensure that the correct amount of exhaust gases is recirculated back into the engine to reduce nitrogen oxide emissions and improve fuel efficiency. If the DPFE sensor fails, it can lead to poor engine performance, increased emissions, and potential check engine light warnings.

What does P0400 OBD trouble code mean and how do you repair it?

P0400 - Exhaust Gas Recirculation Flow Malfunction Possible causes - Exhaust Gas Recirculation (EGR) solenoid valve harness is open or shorted - Exhaust Gas Recirculation (EGR) solenoid valve circuit poor electrical connection - Exhaust Gas Recirculation (EGR) volume control valve stuck closed - Faulty Exhaust Gas Recirculation (EGR) volume control solenoid valve - Dead (Weak) battery - Faulty EGR temperature sensor and circuit - Faulty EGR Valve


What is an egr sensor?

exhaust gas recirculation sensorIt is a sensor that is mounted to the EGR valve. It moniters the position of the EGR valve and sends that info to the ECM.

What does the pressure feedback exhaust sensor do?

According to my Haynes repair manual - the DPFE sensor monitors upstream ( before ) and downstream ( after ) exhaust backpressure . By calculating the difference between the two pressures , the PCM determines exactly the EGR flow rate at all driving conditions
