somewhere during the last session at E-town, my SES light came on. after scanning this morning with my predator, i get these:

P0102 MAF circuit, low input
P0801 Reverse Inhibitor Malfunction
P0803 1-4 skip shift failure

i have an SLP MAF, and tuned out the skip shift. i also have a custom tune, not the predator one, by a speed shop (TTP). what exactly do these codes mean? it seems to be running fine, so dont know about the MAF. i cant get into reverse, without slapping the stick over with my left hand, so theres the rev. inhibitor.......but why did it happen and how do i fix them?

 

Check the fuse box under the hood for a blown sensor fuse.

 

Yep, look for a blown ENG SEN fuse.

 

ill check it tonight

 

turns out it was a blown fuse. question is, why did it blow. they usually blow when a wire shorts, correct. someone else suggested i could have melted a wire.....which one, and where?

 

The 02's are also on that circuit, if you have headers look for a burnt/melted sensor harness against a header.

 

next time shes up on stands ill have to check it out. i had hoped it was just an O2. the wires were made way too tight when i had the headers installed.
