“C13” (P1750) or “C17” (P0105) IAP SENSOR CIRCUIT MALFUNCTION

INSPECTION
Step 1
(When indicating C13/P1750 for IAP sensor #2)

1) Remove the right frame upper cover.

(

VL1500 Service Manual 6-3)

For the other inspection procedures are the same as C17/
P0105.

(When indicating C17/P0105 for IAP sensor #1)

1) Remove the left frame upper cover.

(

VL1500 Service Manual 6-3)

2) Turn the ignition switch OFF.
3) Check the IAP sensor coupler (Front cylinder side

or Rear

cylinder side

) 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

and ground.

7) Also, measure the voltage at the Red wire

and B/Br wire

IAP sensor input voltage: 4.5 – 5.5 V

(

Red –

Ground)

(

Red –

B/Br)

09900-25008: Multi-circuit tester set

Tester knob indication: Voltage (

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.
