Question

P1272 FORD - f250 1995 powerstroke:

What does this code mean? There's been a couple contradictory definitions so it's confusing what to do. Thank you.

Answer 1

1272 High to low side open cylinder 2, this is the injector driver circuit.it usually at the valve cover connector,that causes the open,you can OHM test the low to high side circuit,if it is less than 5 ohms replace the valve cover gasket harness, if it is not you have a short in the UVC harness.
