How do you replace an EGR valve on a 2002 Ford Taurus?

Answer

You don't. You let your Ford dealer do it. They have a 5 year hidden warranty.

Answer

Does the hidden warranty cover cars with almost 100k millage?

Remove the vacumn hose on the top of the EGR valve and plug it. Connect a short hose to the EGR valve. Start the car. Now suck on the hose this will open the EGR valve the engine should stumble and try to die. If it does the EGR valve is working. Their is an "Exhaust gas manifold pressure sensor" that measures the exhaust gas flow to the EGR valve. The problem is the sensor itself becomes clogged with exhaust carbon and gives the computer a fixed false reading, the computer in turn sends too much vacumn to the EGR valve and the engine runs rough, surges and may die. This sensor on the 3.0 cast iron engine ( overhead valve no overhead cam ) is located by the firewall on or near the intake manifold and is connected to an exhaust tube running to the EGR valve by 2 short rubber hoses and has a 3 pin connector. The hoses measure pressure drop across a restriction inside the tube as exhaust gas flows through it to the EGR valve. I've replaced the sensor on 2 different Taurus'es, my wifes 99 and my sons 2002, the cars run great afterwards and the light goes off. About 40 bucks do it yourself easily. Twist the old sensor to loosen the hoses. Push the new sensor onto the hoses. The other engines should have a similar sensor somewhere.
