code 56 What does it mean?
1988 F250 5.0L maunal trans 193K miles
On KOEO I'm getting code 56 which the book say is "MAF circuit above max voltage".
What does that mean and what can I do about it?
I'm also getting other codes, but this is first.

Yup - did it at least twice - got the same code each time. Also got 67 "NDS circuit open with A/C on during set test" and 85 "Cannister Purge circuit failure" and some more that look like auto trans code.
All appear to be repeatable. I haven't don KOER.
