On some OBD II Vehicals Ohio's E-Check (Owned and Operated by
Enviro-Test), they check things via the ALDL connector. What they are doing
is reading the ECM.

I know of a newer ford truck that failed the testing this way because
it had not had trouble codes cleared from the ECM before testing.

If the dealer fixed the problem, as them to remove the trouble codes
from the ECM. Maybe offer to pay half the cost (should not be that high).
Then Drive 50 miles and have the ECM checked for trouble codes. If none,
go to E-check and re-test.

If you reset the ecm you will have to drive it until all the monitors are
complete. This can take several driving cycles and several days. Be aware
that if these cycles aren't complete it will fail. Codes can be looked up at
several sites on the web. Try http://www.diagnosticdialog.com/LookupCode.asp

Sorry to be so vague.

Dealer repaired vehicle about 1.5 years ago. My son purchased the
vehicle about 1 year ago. To pass this years emissions, we cleared
the trouble code (P1810) and drove vehicle until monitors were
complete; however, the P1810 code reappeared at that time.

What I meant earlier was that the dealer has been unresponsive to my
son, the sensor causing the P1810 fault started after they rebuilt the
transmission, but the supposedly fixed it, admitting fault for it
breaking (or something to that effect) but to our knowledge it has had
a fault code ever since. I just want a little info about the sensor
from the dealer, which they don't want to be helpful with (I think
they at least owe us that, considering the fault history).

I would like to find out if the sensor is accessible at all, like a
coolant sensor would be, or if instead it is internal to the
transmission. Is there a connector I could check, because in my
experience connections cause most electronic problems.

Or even, what is the likelihood that the dealer is the ultimate
culprit here, with their transmission rebuild and all, have they
caused a chronic problem?

Thanks,

Go to Helminc and order the service manual for the car. Then you can
troubleshoot the problem. Don't expect a dealer service rep to give you
information so you can fix it yourself.

1810= internal slippage detected
what year is the van ?

a lot a valve body problem at the 4 gear spool valve causing excessive
slippage
this could be a valve body or worse a trans rebuild ,steve

That's not what P1810 is on this vehicle..
