Judgment of presence or absence of deteriorated characteristics
of the air flow sensor
a.
If the detected air flow rate of the air flow sensor mounted to
the vehicle shows a decrease by 10% or more in comparison
with that of a new air flow sensor (See the following for the
calculating formula), the air flow sensor mounted to the vehi-
cle is deteriorated. Restore the vehicle with a new air flow
sensor mounted before finishing the inspection.
Calculation formula: {(B)-(A)}/(B) × 100
>
10
b.
If the both air flow sensors show an equal flow rate, the air
flow sensor mounted to the vehicle functions normally. Mount
the original air flow sensor again before finishing the inspec-
tion.
Tightening Torque:
0.56-0.82 N·m {5.8-8.3 kgf·cm, 0.42-0.60 lbf·ft}
! CAUTION
•
The flow rate detecting element (wire) is processed with
extreme ingenuity. Do not directly touch the detecting ele-
ment (wire) to prevent breakage.
•
Do not apply excessive torque to the air flow sensor mount-
ing screw (M 3.5) when tightening it.
