FI SYSTEM TROUBLESHOOTING
“C17” (P0105-H/L) IAP SENSOR CIRCUIT MALFUNCTION

INSPECTION
Step 1 (When indicating C17:)

1) Turn the ignition switch OFF.
2) Remove the engine mounting left upper bracket

1

by remov-

ing the bolts

LT-R450K8 3-6)

DETECTED CONDITION

POSSIBLE CAUSE

C17

IAP sensor voltage is not within the fol-
lowing range.
0.2 V

Sensor voltage < 4.1 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.

• IAP sensor circuit shorted to VCC or ground cir-

cuit open.

• IAP sensor circuit open or shorted to ground or

VCC circuit open.

L

Sensor voltage is lower than specified
value.
