No, the EGR valve and the DPFE sensor are not the same thing. The EGR (Exhaust Gas Recirculation) valve is responsible for recirculating a portion of the exhaust gases back into the engine's intake to reduce emissions and improve efficiency. The DPFE (Differential Pressure Feedback EGR) sensor, on the other hand, measures the pressure difference across the EGR system to monitor its operation and ensure proper functionality. They work together but serve distinct roles in the vehicle's emissions control system.
What else can I help you with?
1993 Lincoln town car is DPFE sensor the same as EGR valve position sensor if not where is the DPFE sensor located?
The DPFE sensor is a totally separate sensor. Look for the feed pipe to the EGR valve and follow it towards the exhaust. Somewhere along that line you will see two small pipes leading to hoses, that lead to the sensor.
Is the throttle position sensor and the idle control valve the same thing?
No
Would a bad 02 sensor make the egr valve malfuction?
I have the same thing wring with mine. The auto place told me that the egr valve will make the o2 sensor seem bad, so now im going to change the egr valve and hope the o2 senor is still good.Wait!Before changing the EGR valve, please look through the "Related Questions" below. The valve might be fine and it's a DPFE sensor, or the valve and secondary air system just need a cleaning.Don't throw money at replacing something just yet...See "Related Questions" below for more
Why does the check engine light keep reoccuring with the same code PO401 EGR valve after the EGR valve was replaced This is on a Ford Explorer Sport Trac?
The OBD 2 code, P0401 means "low flow". The most common cause of this code with any Ford vehicle is the DPFE sensor, NOT the E.G.R. Other causes could be blocked passages for the EGR, or leaking or restricted hoses that go to the DPFE. == ==
1996 ford f-150 302 I have changed egr valve egr line to intake manifold and egr vacuum solenoid drives good for short distance and check engine light says egr insufficient flow?
i have the same truck and the same problem. i have only replaced the egr valve, iac valve, and o2 sensors. I've read some threads of later model trucks with a possible dpfe sensor problem instead thoughdpfe sensor or carbon build up inside the intake
Is the idle air control valve the same thing as an oxygen sensor?
No.Idle air control valve is used by the vehicle ECU to control the idle speed.The O2 sensor measures the oxygen in the exhaust gas and sends a signal to the ECU which controls the fuel being injected into the engine
Is crank sensor and knock sensor on 2000 villager same thing?
no, it is not.
Is a crankshaft sensor and crank position sensor the same thing?
Yes it is.
Is the crank position sensor and crankshaft sensor the same in a 96 Jeep Laredo?
yes same thing
Is the crankshaft position sensor and engine speed sensor the same thing on a 2004 Nissan altima?
is the crankshaft position sensor the same and the engine speed sensor
Is their a maps and a boost sensor on dodge diesel?
The map sensor and boost pressure sensor are the same thing.
Is a crank or cam positing censor the same thing?
No, a crank position sensor and a cam position sensor are not the same thing. The crank position sensor monitors the position and rotational speed of the crankshaft, which is crucial for engine timing and fuel injection. In contrast, the cam position sensor tracks the position of the camshaft, helping to manage valve timing and ensure proper engine performance. Both sensors are vital for engine management but serve different functions.
