Error Code 22 and MAP checks good
An old workhorse, 84 E150 4.9 L 6
Still getting KOEO code 22 even tho the MAP IS sending the correct frequency for vacuum readings from 0 to 19 in.
All other sensors are reading correctly, no errors there.
All wiring, grounds checked. MAP tested on my bench with O scope, and all readings correspond.
Rechecked the MAP back in the truck and signal IS correct. Looked in the computer and no obvious problems, the three electrolytic capacitors test good on cap tester.
Where now?
