1A-25 Engine General Information and Diagnosis:

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

Detected Condition and Possible Cause
Detected Condition
IAP sensor voltage is not within the following range.
0.24 V ≤ Sensor voltage < 4.10 V
NOTE
• Note that atmospheric pressure varies
depending on weather conditions as well
as altitude.
Take that into consideration when
inspecting voltage.
• If SDS is used, P0105-H is indicated when
sensor voltage is higher than specified
value.
• If SDS is used, P0105-L is indicated when
sensor voltage is lower than specified
value.
Wiring Diagram
IAP sensor
• 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.
NOTE
• When P0105-H is displayed, it is possible that
IAP sensor circuit is open or shorted to Vcc
or ground circuit is open.
• When P0105-L is displayed, it is possible that
IAP sensor circuit is shorted to ground or
Vcc circuit is open.
