It stands for Exhaust Gas Recirculation tube.
It is called the egr tube.
that my friend is the tube that goes from the exhaust manifold to the egr valve make...
EGR sensor ( gas temperature sensor ) is monted near the EGR valve, which is install into the EGR tube.
You have to remove the egr tube, vacuum source and two bolts. the tube can be quite difficult. Generally the DPFE sensor on Fords is the cause of an EGR problem though.
The EGR valve and electrical transducer should be replaced at the same time as they are matched. Remove EGR transducer from the air inlet duct. Disconnect vacuum supply tube from EGR transducer solenoid. Remove air inlet duct. Remove EGR tube to EGR valve screws. Remove EGR valve mounting screws. Remove EGR valve and transducer. Clean gasket surfaces. Discard old gaskets. If necessary, clean EGR passages. Loosely install EGR valve with new gaskets and finer tighten EGR tube fasteners. Tighten tube fasteners to 95 in lb, tighten EGR valve mounting screws to 200 in lb. Install air inlet duct. Connect vacuum supply tube to solenoid. Attach electrical connector to solenoid. Install EGR transducer onto air inlet duct.
Plugged egr tube or a failed egr valve.
EGR vavle is clogged go to "you tube" search "clean EGR "
egr, low flow problem.clean out egr and tube, of carbon.
look at the focus fanatics forum... this thread should help http://forums.focaljet.com/spi-tuning/503448-egr-tube-sheared-header.html
It's called the EGR tube.
THE EGR VALVE CAN BE FOUND IF YOU REMOVE THE INJET. COVER YOU WILL BE ABLE TO SEE IT LOOKS LIKE A MUSHROOM. BYT MAKE SURE YOU CLEAN THE EGR TUBE ALSO. Answer : EGR is mounted behind the throttle body with a metal exhaust tube ( use lubricant to loosen rust) and vacuum line on top. Check DPFE as well, rec replace controls egr valve. replace if code said excessive egr flow.
If your car has the 2.5L engine. The EGR valve is located directly under the coolant fill cap & pipe. The EGR has a long metal tube that goes from the EGR valve to the upper intake plenum.
