1998 Ford E-Series Van EGR Valve

can i ask why you are replacing it?

The check engine light is on and the code read EGR problem.

I have been experiencing all the problems associated with a bad valve and cannont pass emissions w/o its replacement.

My van is actually a 1996, '98 is a typo.

99 percent of the time the problem is not the valve but in fact the sensor that detects valve operation. this sensor (dpfe) takes about 5 minutes to replace. its held in by 2 8mm bolts and has two fat rubber hoses going to it. it usually gives a code 401 or 402. low flow or too much flow. try this first then get back to me if it does not fix the problem.
