it is located at the rear of the engine behind the intake, the most common symptom on this is just a rough idle or in most cases a check engine light that stays on, no matter what is wrong with the valve it will set a fault code and turn the check engine light on, so unless the light is on the problem is not the EGR
I am fixing to change my EGR valve and the piece of paper that came with the part say this:
Before installing this part, check the EGR valve passage in the intake manifold and clear any carbon blockage. Failure to do so will result in repeat malfuntion of the EGR valve system. Refer to a technical service manual or contact a service dealer for proper cleaning procedures.
its easy too replace but you need too reset your cmputer first too see if the light stays out before you go and buy the egr valve
disconnect the pos side of the battery for 5 min that will reset the computer,if the light comes back on then get the egr valve then you will have too reset it again
Hello, I have had the same problem and turned out to be the EGR valve position sensor. The sensor is part of the car's emissions system and it regulates the position of the EGR valve by sending voltage readings to the computer under the dash. Wrong voltage will give wrong position readings to the computer and the computer will open it too far which causes the car to have a flat spot. You can disconnect the EGR valve to see if that solves the problem before replacing anything. The EGR valve is closed when the engine is cold all of the time if working properly and opens under various conditions when engine warms to reduce NOX emissions.
No Biggy.. Get them to install a DPFE sensor,, ( its the one that regulates the EGR valve ) Most ppl mistake a 1409 Code as Being EGR and it is kinda.. but when the valve maint fails.. its almost always the DPFE sensor.. Try that and lemmie know
Insufficient EGRFlow Detected Possible Causes: DPFE sensor signal circuit is shorted to ground DPFE sensor VREF circuit is open between sensor and PCM DPFE sensor downstream hose off or plugged DPFE sensor hoses both off, loose or damaged DPFE sensor hoses connected wrong (reversed) EGR orifice tube is damaged or restricted PCM has failed And what sets the code is…….Engine started, engine running in closed loop under steady cruise conditions, and the PCM detected the DPFE sensor input indicated insufficient EGR gas flow. Run the KOER Self-Test, and if DTC P1408 is present, the fault is currently present. This code sets in 2 Trip(s). The light will stay on until the cause is repaired. A bad EGR valve is only on possible cause. Hope this helps, Dave
