AFL reads 100%
 

my AFL reading on my safc 2 says 100%

i checked if my mass air flow was plugged in and it is


so what else could be casuing this and how do i fix it

Have you re-initialized the S-AFC?

Also select monitor mode & look at the voltages.

check your TPS. if its not plugged is going to read 100% on the safc( it has happened to me).

no i have not re intialized the safc everything was working fine the previous day .. and now it is all over the place.

what kinda voltages am i looking for?

Key on, engine off, it should read approx 4vdc for afl

TPS should read approx 1vdc key on, engine off and a HOT engine.
