Ford Explorer: EGR valve

It's not a good idea to replace either the valve or the 'sensor', based on
what the 'dude' at Napa said after hearing what the 'dude' at Autozone made
out of the trouble code. In fact, it's a bad idea to replace any parts
without actually determining first that they are defective. Contrary to what
some may believe, the self-diagnostic capabilities of today's engines are
not yet at the point of determining which part is bad. All they can do is
point a general direction. It still takes some skill, time and tools to
figure out what is actually wrong.
If you want advice, please post the details of the vehicle (year, engine
type, mileage), the actual trouble code, and any other description of the
problem besides the fact that the CEL is on (does the engine hesitate at
idle, miss, accelerate poorly?)

Thanks for stating what I suspected anyway!!

There really are no symptoms other than the light on the dash is on. In
fact, it was off for a period today, then when i got gas it came on again.
I made sure the cap was on securely and correctly.
Until other symptoms show up, should I just ignore the light?

Thanks

Probably not what you wanted to hear, but no, you should not ignore the
light. It's telling you that something is wrong with your vehicle, and it
needs to be diagnosed and repaired. It could cost much more if you ignore
it, or even leave you stranded somewhere. So be nice to the air that we all
breathe (to quote Jim Warman), do us a favor and fix it, OK?

I must assume (dang, doing that lot's, somedays...) that the code you
received is P0401 (a year and engine size might help....).

There are many things that can trigger most of the EGR related codes - OBD1
and OBD2 are light years apart in self testing capabilities.

There's just not much to be said without some more information.
