They are not screws they are bolts either 1omm or 13mm
yes it is located on the top of the manifold, back side of the motor next to the throttle assembly shield. It is electronically controlled
As I recall, that engine does not have an EGR valve.
its the hose coming off of the valve cover that's the egr valve
if this is a v6, unless your car has California emissions, there is no EGR valve.
1990 -1993 injected Festivas do not have a EGR valve
The 1993 Ford escort did not come with an EGR valve. It is one of a few year models that do not have one.
As far as I can tell, there is no EGR valve on 1993 Ford Aerostar 3.0L engines. I have searched and found none and the vacuum hose routing decal in the engine compartment does not show an EGR valve.
It is a 50 EGR Valve. You can use it for '93-'97 Dodge Dakota, Ram 1500, 2500, or Jeep.
The EGR position sensor is located on top of the EGR valve. Has an electrical connector attached.
The P1406 code on a 1996 Oldsmobile Cutlass Ciera 3.1 is the code for the EGR pintle position circuit. I know this because it was my question initially and we bought a code reader to check the problem. It is a factory specific code, so the answer is quite specific. Good luck !
I have a 93 4.0 and it has no EGR valve. My neighbor who is a ford mech. says some don't have EGR's and some have only one O2 sensor.
The Red line is the Vacumme line the comes from the drivers side of the intake to the EGR selonoid (at the top) the Green line goes from the EGR selonoid directly to the EGR valve (at the bottom of the Selonoid).
Start the engine, and spray a little carb cleaner around and on the EGR valve. If the engine changes sound are idles up are down then the valve is bad.
If it is an electronic EGR valve it is on the top of the engine on the rear left or drivers side it has three solenoids and a wire harness at the top IF YOU HAVE THE V6 (3.3) ENGINE IT DOES NOT HAVE AN EGR VALVE. IF YOU HAVE THE 2.2 4 CYL YOU HAVE A VACUUM TYPE EGR LOCATED ON THE END OF THE HEAD ABOVE THE TRANS.
Its a 3300 3.3 3.1?? drivers side rear coner of engine (top of). Its an electronic EGR with 3 valves on it. REmove it and check the passageway below it as it carbons up and will give you an EGR failure code/symptom
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.
Some vehicles dont have EGR Valve... I have a 90 Caravan, same engine as yours, basically the same thing as what you have and it has the EGR valve, then again, same engine in my 92 Dodge Spirit and it has no EGR Valve... the EGR is just mainly an emissions thing to help keep down on air polution. If yours did have the EGR Valve, they are really easy to spot, its on the left of the throttle body and the EGR Valve even says EGR right on top of it, so if you do have the valve you will know it very easily with or without any book or diagrams.
On the 4.0 L OHV engine, the EGR valve is located on the driver's side of the engine. how do i repair it
Check your EGR valve Check EGR valve
check egr system,make sure vacuum reaches egr valve when is supposed to
It means that either your EGR solenoid or EGR valve is bad. The EGR valve sometimes sticks open due to carbon build-up. This can be fixed by removing it and cleaning the valve piston with carburetor cleaner and a metal brush. The EGR valve could also have a bad diaphragm. You can check this by connecting a vacuum hand pump to the EGR valve and checking to see if the valve holds vacuum. If it does not, that means the diaphragm is ripped and the valve will need to be replaced. If neither of these seem to be the problem then you have a faulty EGR solenoid. EGR solenoid replacement is very simple and only takes about 5 minutes.
It is an electrically operated valve that when energized let's the vacuum through to the EGR valve to open it. Many also contain an electical switch that is closed when the vacuum is applied to the EGR valve to send a confirmation signal back to the ECM (engine control module).
Should be at the front of the motor under the air breather on your intake.
