Why does an EGR valve need to be open?
The warmth of the exhaust lets the combustion chambers warm up quickly, while the spent, inert gases keep the chambers from getting too hot when the engine fully warms up. Whether mechanical or electronic, EGR valves open and close to control the gas flow.
Where is the EGR valve on a 2006 Ford Mondeo?
Where is the EGR valve on a 2006 Ford Mondeo? Follow the air intake past the air filter, and it should go right into the engine. It should pass through a box right before it goes into the engine. That’s you’re throttle body. There should be a box or a can looking container attached off the side, right by that part of the air intake.

How many wires are in an EGR valve?
There are 5 wires sticking out of the EGR valve’s connector, in this section we’ll explore what each one does. Most of the EGR valves will have the letters A thru’ E molded onto the EGR valve’s connector.
