These requirements have to be met in your first order from this site. Cart Summary Product Qty. Your cart contains more than 10 items. Click to modify cart items.

Product Number This kit contains the following components. The problem may be nothing more than a loose or corroded wiring connector. Check the solenoid's resistance with ah ohm meter. If the solenoid is shorted, open or out of specifications, replace it.

Inspect the EGR valve itself. Because of the valve's location, it may be difficult to see whether or not the valve stem moves when the engine is revved to to rpm by slowing opening and closing the throttle.

The EGR valve stem should move if the valve is functioning correctly. A hand mirror may make it easier to watch the valve stem. Be careful not to touch the valve because it will be hot!

If the valve stem doesn't move when the engine is revved and the valve is receiving vacuum , there may be something wrong with the EGR valve. Vacuum should pull the valve open creating the equivalent of a large vacuum leak.

This should cause a momentary drop in idle speed and a noticeable increase in idle roughness. Remove and inspect the EGR valve if you suspect a problem. Most failures are caused by a rupture or leak in the valve diaphragm. If the valve is not a backpressure type, it should hold vacuum when vacuum is applied with a hand-help pump. If it can't hold vacuum, it needs to be replaced. Note: This test does not work on backpressure EGR valves. Backpressure EGR valves sometimes fail if the hollow valve stem becomes clogged with carbon or debris.

This you can see for yourself. It's almost impossible to remove such a clog, so replace the EGR valve. Carbon accumulations around the base of the EGR valve can sometimes interfere with the opening or closing of the valve. These can be removed by careful brushing or by soaking the tip of the valve in solvent. Do not soak the entire valve in solvent or allow solvent to get anywhere near the diaphragm.

Furthermore, you can have box sync up with your local files as long as you put them in the right place! If you need to work offline, you can, and when you are back on the Duke network, Box will automatically back up your files.

You will also be able to share files with TAs if necessary. Note: - if you have a new Mac with the M1 chip, you may be able to get Box Drive to work but if not, you will still be able to do all the work for the class but your files will not be backed up to the cloud. Try to get Box Drive working, but if it fails, you should make a folder on your main drive called EGRS22mac and use it to store all the files for this class until we figure out the issue with the M1.

Skip the steps below regarding Box Drive. This semester, we will be using a freemium tool called Overleaf for making lab documents. We will only need the free features for work this semester.
