Re: what does EGR bypass do

Little plug next to the fuel filter and what is does is sends exhaust back in the intake. Think of running a marathon, putting a garden hose up your butt, than when you are needing fresh air badly, put the other end of the hose in your mouth. Yuk!!! Well how good do you think that would be for your performance? Dirty exhaust does not really do a lot of good for your engine. Unplugging it may set a code.

Re: what does EGR bypass do

But the exhaust gases are cooled, via an EGR cooler. Its not just hot exhaust back into the motor..

Throw an air purifier/filter into the garden hose analogy and you will probably closer to explaining EGR...

Re: what does EGR bypass do

The egr should be closed at wide open throttle anyway, I couldnt see how it would help.

Re: what does EGR bypass do

It is definitely for emission purposes. And it will set a code if you unplug it. Some guys have bought a spare and plugged it in instead and just wire tied it out of the way so the computer still thinks it is hooked up. It (the factory ECR valve along with the related exhaust gas pressure sensor) has been source of a lot of problems. The ECR valve is famous for sticking and the exhaust gas pressure sensor is knows to fail - at about 10,000 mile intervals. This is straight from the Ford mechanic. Ford is working on new designs for the pressure sensor.

Re: what does egr bypass do

the biggest problem with egr is, in conjunction with crankcase vent, they make a nice combination of diesel soot and oil droplets which cake up on the intake and eventually clog it.
