Test it with a vacuum hand pump.
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.
hopw do I find the egr valve on a vauxhall signum
Remove the EGR valve from the Corsa. Wash the EGR valve with carburetor cleaner. Make sure that the valve is clean of gunk and let it dry. Reinstall the valve.
i want to know if a 2004 grand am , 2.2 engine has a egr valve
Never heard of an EGR pump and need to know what year, make, model, engine and what valve you are looking for.
Realley need to no what your working on and the year.
The EGR valve is located at the front of the h22a4 engine. The EGR valve is right beside of the front of the EGR valve.
If you want to locate a new egr valve, check with your local auto parts store. If you want to know where the egr valve is located on your vehicle, post the year and engine size of your S10.
Not sure what a Dodge Adventure is, Trucks did not have EGR in 2000, minivans and cars did.
I don't know if it is the same but the EGR valve on my 1977 Ford 302 was underneath the carburetor at the back of a spacer
it usually means the the EGR valve needs to be replaced. If your car is "bucking" on start up then for sure it is the EGR valve.
Assuming you mean the egr valve, I would make sure that you have the check engine codes cleared. In addition, are you sure that it was truly the egr valve, and not the DPFE sensor monitoring the valve?
