While your engine doesn't sound like it's covered (checking OASIS is the
surest way to tell), I'd be hard pressed to say that this isn't the cause of
your concern. All the same, even though this is THE popular cause of this
code, a modicum of testing should happem if we're using our own nickel.

This particular failure isn't addressed with a Field Service Action
(Fordspeak for recall) but is covered under what is called a Customer
Satisfaction Program. In all honesty, I have performed many repairs I
thought were retail but a quick OASIS check showed they would be coverred
under warranty..... not many techs check OASIS with enough regularity.
Before anyone gets on a high horse about Ford let's remind ourselves that
each and every company out there makes a living by taking money from
customers (as much as they can) and giving it to the shareholders. In the
book "On A Clear Day, You Can See General Motors", an un-named, high level
exec was quoted as saying "General Motors is NOT in the business of building
cars..... GM is in the business of making money....".

FWIW, you can PM me your VIN, be sure to remind me why in the message (old
fart stuff) and I can see for sure if you're coverred under the CSP...

HTH
