5-32 FI SYSTEM DIAGNOSIS
“C13” (P0105) IAP SENSOR CIRCUIT MALFUNCTION
INSPECTION
Step 1
1) Remove the left side cover. (
$
8-8)
2) Turn the ignition switch OFF.
3) Check the IAP sensor coupler for loose or poor contacts.
If OK, then measure the IAP sensor input voltage.
DETECTED CONDITION
POSSIBLE CAUSE
C13
IAP sensor voltage is not within the fol-
lowing range.
0.5 V < Sensor voltage
4.85 V
NOTE:
Note that atmospheric pressure varies
depending on weather conditions as
well as altitude.
Take that into consideration when
inspecting voltage.
• Clogged vacuum passage between throttle body
and IAP sensor.
• Air being drawn from vacuum passage between
throttle body and IAP sensor.
• IAP sensor circuit open or shorted to ground.
• IAP sensor malfunction.
• ECM malfunction.
P0105 H Sensor voltage is higher than specified
value.
L
Sensor voltage is lower than specified
value.
