Where is the EGR valve on a Ford Escape?
Right in front of the EGR valve, there is a metal tube. Follow it back behind the motor and at the bottom of it there is a rubber hose about 2 inches long that had come off the fitting. The fitting (as you’re looking at the motor from the front) is just to the left of the EGR valve.
Can a check engine light get clogged up?
The EGR valve can get clogged up or fail entirely. If you’re even slightly mechanically inclined, you can remove the valve, clean it up, and reinstall it in a relatively short amount of time. If the valve needs to be replaced, expect to pay at least $125 for a brand-new, OEM-quality unit.
How can I find out if my vacuum is leaking?
Any search for vacuum leaks should start out with one important tool: a vacuum hose diagram. This is sometimes printed on a placard in the engine bay. If not, look one up in the service manual or consult an online service such as AllData. You don’t want to haphazardly spray carb cleaner on the wrong line.
Can a smoke generator get rid of a vacuum leak?
It’s a pro-grade tool, but a smoke generator makes chasing down vacuum leaks simple. These leaks tend to come in bunches, since rubber hoses and plastic vacuum fittings deteriorate as a car ages. Keep hunting until you’ve found them all. 1.
Can a vacuum be used to open an EGR valve?
A vacuum-operated EGR valve is usually only found in older vehicles. It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open. The vacuum is often regulated by a computer-controlled solenoid.
What are the symptoms of a failing EGR valve?
What are the symptoms of a failing EGR valve? A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.
How does exhaust gas recirculation ( EGR ) work in an engine?
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine’s exhaust gas back to the engine cylinders.
Why does my engine stall when the EGR is open?
This is because the temperature is lower so fuel does not burn at the optimal temperature and as a result is less efficient. Stalling when the engine idles like a rough idle is usually caused when the EGR valve is permanently open and is constantly letting exhaust gases into the EGR system.
The EGR valve sits on the top of the engine near the rear of the block and looks like a round disk with a small vacuum tube attached to the top center of the disk. A steel tube runs from the base of the valve to the exhaust manifold that threads into the side of the EGR valve. Open the hood and locate the EGR valve.
What to do if your EGR valve is blocked?
When the EGR valve is blocked, error codes of P1404 and P1406 may display on the engine light area. Remove the plug and clean it using the valve cleaning kit to remove blockages.
How do you remove an EGR gasket from an engine?
Locate the nut on the tube where it meets the EGR valve and turn it counterclockwise with a wrench and then pull the tube away from the valve. Locate and remove the two bolts on the base of the EGR valve with a socket and ratchet and then remove the valve and gasket from the engine.
How does an EGR valve work on a diesel engine?
When you slowly and efficiently come to a stop, the valve also closes and stops the flow of exhaust gases. The process continues so long as the engine is operating. Once you shut off the engine, the valve also closes and stays in that position. Diesel and gasoline-powered engines can use an array of EGR valve configurations.

What happens if you have a bad EGR valve?
When the valve is opened, exhaust gases are allowed through the vehicle’s EGR system to help control vehicle emissions. When the EGR valve has an issue, it can cause problems with the flow and operation of the EGR system, which can lead to increased emissions and performance issues. Usually, a bad or failing EGR valve will produce any these 4…
How does an exhaust gas recirculation ( EGR ) valve work?
The EGR (Exhaust Gas Recirculation) valve helps lower the car’s exhaust emissions (gases from the tailpipe). It recirculates the portion of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby reducing the emissions. The EGR
