po 102 code maf sensor circut low 2013 toyota venza 2.7 replaced checked single wire 1.8 to 4.9 snap throttle looks good but have permanent code still i think wire broke between sensor
and pcm worndering this because scanner shows data pid up and down and if wire is broken are these substituted values.
A permanent code and a current code are not the same thing.
A permanent code will not stop from passing a state inspection, and will not illuminate the check engine light.
You can fix a problem, clear the current codes, and a permanent code will remain until the computer is satisfied that the system is working as intended.
