Check for vacuum leaks. Use a can of GumOut to spray around vacuum hoses, while the motor is running, if the idle increases when sprayed on or around a certain hose, check that hose for leaks.

SOURCE: I have a 1979 El

There should be a vacuum diagram under the hood but if it's gone the EGR hooks to the purple topped vacum port. I think that's the one on the thermostat housing, if I remember right. The other vacuum port should have a red and white restrictor valve in one of the lines and that is the wrong one. The other line from it goes to the bottom left on the carburator. If you don't have any of that stuff, and that's possible, then it needs to have manifold vacuum so hook it direct to the carb or the manifold on an available nipple. Hope this helps.

Where is the egr solenoid located

EGR vacuum solenoid is located below your EGR valve. Center your self on the engine, look between the rear of the engine and your firewall. You can see your the top of you EGR valve, there will be a small vacuum hose connected to the top. Follow that small hose straight down from your EGR valve and it connects to the solenoid. You can see the solenoid better from beneath the car. May have an orange connector. Hope this helps.

PO401 EGR , the ECM has detected too little flow

The EGR valve is towards the firewall and looks like a flying saucer with either a vacuum hose or electrical connectors attached to it.EGR stands for exhaust gas regulator. So this item has to be connected to your exhaust manifold. During engine operations in order to cool off combustion temperatures this valve opens and permits exhaust gases into combustion chamber.
Your code is saying that its passage way is clogged ,the valve is either stuck closed ,the vacuum or electrical system that control it are defective. I recommend you get the repair manual for this vehicle there are several types of EGR valves and the testing procedure are different for each one. If your good with a voltmeter than getting the manual for this vehicle is gonna save you a fortune.
The easiest thing to do when you locate the valve is to remove it, use gun out and spray the passage way it sits on . Then clean the valve itself. If it has a vacuum port hook it up to a vacuum pump and see if it holds vacuum ( about 3-5 hg's) and its pintel moves. if it does than valve is ok. Then replace gasket and install valve. If valve has electrical connectors then clean passage and valve replace gasket and install valve.Your gonna have to go to Autozone again to have them erase code before you know for sure you repaired the item. Good luck

Random missfire all cylinders 1996 honda civic sohc

Check the EGR valve system. Honda's are prone to the exhaust supply to the EGR valve getting clogged with carbon at the valve port entrance. A clogged EGR valve can cause the engine combustion temperature to climb and then for pre-ignition miss-fire events to become common. The EGR is located inside the elbow of the air filter pipe at the back of the engine on the left beneath the coil. Anything you can temporarily remove to provide access the better. The EGR valve has two bolts, an electrical connector and a vacuum line attached to its top. Take it off and give it a really good clean, carburettor or brake cleaner works well in conjunction with cloths and brushes. Once cleaned like new replace everything including the vacuum line and electrical connector.

How do you replace the egr valve in a 1997 chrysler concorde lx

Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System

This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses

Component and System Testing
  1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
  2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
  3. Be sure the electrical connector is firmly attached at the valve control.
  4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
  5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.

Need location of the erg sensor 2000 ford ranger

The egr valve has two sensors. One is an EGR position sensor which is physically attached to the EGR valve. The other sensor is the DPFE (Delta Pressure Feedback EGR) sensor, commonly called the EGR pressure sensor. It's location varies depending on the engine you have. You can fine this sensor by following the vacuum hose on the EGR valve. It will be with in inches of the EGR valve. The sensor will be black (plastic) or silver (metal), have two or three vacuum ports and an electrical connection on it.

The vacuum pressure sensor is a high failure item on fords. Any Ford parts department will have one in stock, as well as some aftermarket parts stores.

The new sensor may not look exactly the same as the old part, but will have all the hook ups as the old one. You may also need to replace the vacuum hose to the sensor as well

No vacuum to egr valve

there is an EGR vacuum solenoid somwhere that controls on/off vacuum to actuate the valve. i am not to sure of the location, but follow the vacuum line back from the egr until you find a device that looks like an electrical check valve for vacuum. that is a possibilty. but then again i am a ford,chrysler guy and am just giving you an answer based on my understanding of the functuality of a vacuum egr system

If it's a 2.0L, 5 speed (1994-7) there are two DPFE solenoids (both w/ 3 vacuum ports) near the oil filter, which control the EGR valve. They are discontinued and impossible to find except on junked cars. (FORD #'s K5T44093-4)
