Does Ford Focus have EGR?
The exhaust gas recirculation valve is part of your Ford Focus emission control system. It allows emission gases to enter the intake manifold at specific driving conditions. It is common for the valve passages to clog and the valve stem to bind.
Can EGR valve be cleaned?
To clean the valve, wear an acid-resistant pair of gloves. Put on safety glasses, too, as the carbon deposits could become airborne in the process. Spray the EGR valve cleaner onto the carbon deposits. Remove the carbon buildup with the use of a pipe cleaning brush and dull scraper.
What does the EGR valve do?
It connects the exhaust manifold to the intake manifold and is controlled by either a vacuum or a built-in electric step motor. The function of the EGR valve is to control the flow of exhaust gas being recirculated depending on the engine load.
Can the EGR valve cause starting problems?
The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases; into the intake manifold to get re-burned. But, the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting.
What happens if I unplug EGR valve?
If you unplug it, while the truck is off, then the EGR will stay closed. If the EGR valve is clogged or completely blocked off it can longer re-burn harmful emissions in the combustion chamber. You’re now sending the exhaust gas away from the engine when using an EGR delete kit, which means it begins to run cleaner.
How much does it cost to fix EGR valve?
It will cost you between $150 and $700 to get your EGR valve replaced by a mechanic. If you’re interested in just getting the parts on your own, you can head to AutoZone and buy a new one at prices that range from as low as $40 to as high as $500.
What causes an EGR to fail?
The failure of the EGR valve on the vehicle is not out of the ordinary, as this issue can arise on most modern diesel engines. The failures are usually caused by a build-up of deposits in the EGR valve over a period of time that causes them to stick.
