I had the check engine light illuminate on my 97 Ford Explorer (105K
miles). Took it to repair shop and they told me it was a Cam Sensor. I
had them perform the repair. When the gave the truck back, the light
was still on. They told me that it had to re-learn the engine and that
it would go off in about a week. I took it back a week later and they
quizzed me on how the truck was driven. When I told them it was my
wife's vehicle and she had only driven it locally around town for about
80 miles with top speed being 50 they told me that it had to be driven
over 65 mph for at least 30 minutes as part of the learning process. So
I took it to work a couple of times, 26 miles each way most of it at
high speed. When I took it back today they first told me the code for
the cam sensor was still in the computer, then when the forman looked it
up he printed out a diagnostic that said on a single trip I must drive
the vehicle at slow speed for 10-15 minutes with 4 idles (do not turn
off engine) following one of the idles I must accelerate at faster than
1/2 throttle. Then I must drive at 65 MPH for 15-20 minutes.

This sounds like BS to me. Since I do not have a code reader I am at
their mercy to pay for and fix what they claim needs fixing. Now that
it does not turn off the check engine light I likewise am at their mercy
concerning while the check engine light is still on. Any suggestions?
Does what they say make sense?

Your right , it is

You can clear dtc's and the engine has to re-learn new strategy, but if car
is fixed, light should stay off.

What kind of shop is this??

If the shop cares about you as a customer and their appearance as a
professional facility that does good work, they would clear any codes, road
test the vehicle and recheck for codes to verify the repair. Anything less
is unconscionable.

If yours is a push rod 4.0, a special tool is required to properly
synchronize the sensor during installation..... there is no "learn" period.
It is either right or it is wrong (meaning a botched repair). If yours is
the OHC 4.0, no alignment tool is required but, again, there is no "learn"
period.

Your BS detector is operating well..... this sounding like about a level 8
BS alert....

It's pretty obvious that this shop has no understanding of the system and no
apparent desire to learn about it....
