“C13” (P1750) or “C17” (P0105) IAP SENSOR CIRCUIT MALFUNCTION
INSPECTION
Step 1
(When indicating C13/P1750 for IAP sensor #2)
1) For the other inspection procedures are the same as C17/
P0105.
(When indicating C17/P0105 for IAP sensor #1)
1) Remove the fuel tank. (
6-3)
2) Turn the ignition switch OFF.
3) Check the IAP sensor coupler (Front cylinder side
1
or Rear
cylinder side
2
) for loose or poor contacts.
If OK, then measure the IAP sensor input voltage.
4) Disconnect the IAP sensor coupler.
5) Turn the ignition switch ON.
6) Measure the voltage at the Red wire
3
and ground.
7) Also, measure the voltage at the Red wire
3
and B/Br wire
4
.
IAP sensor input voltage: 4.5 – 5.5 V

DETECTED CONDITION
POSSIBLE CAUSE
IAP sensor voltage low or high
(0.1 V
Sensor voltage < 4.8 V)
NOTE:
Note that atmospheric pressure varies depending on
weather conditions as well as altitude.
Take that into consideration when inspecting volt-
age.
• 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
