Dtc "C13" (P1750-H/L) Or "C17" (P0105-H/L): Iap Sensor Circuit Malfunction - Suzuki VLR1800 Service Manual

DTC "C13" (P1750-H/L) or "C17" (P0105-H/L): IAP Sensor Circuit Malfunction

Detected Condition and Possible Cause
Detected Condition
IAP sensor voltage is not within the
following range.
0.5 V ≤ Sensor voltage < 4.85 V
NOTE
Note that atmospheric pressure
C13/C17
varies depending on weather
conditions as well as altitude.
Take that into consideration
when inspecting voltage.
Sensor voltage is higher than specified
H
P1750/ value.
P0105 Sensor voltage is lower than specified
L
value.

Engine General Information and Diagnosis:
Possible Cause
• 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.
• IAP sensor circuit is open or shorted to VCC or ground
circuit open.
• IAP sensor circuit is shorted to ground or VCC circuit
open.
