DETECTED CONDITION AND POSSIBLE CAUSE
WIRING DIAGRAM
TROUBLESHOOTING
NOTE:
After repairing the trouble, clear the DTC using SDS tool. (4-25)
DETECTED CONDITION POSSIBLE CAUSE
C13/C17 IAP sensor voltage is not within the fol-
lowing range.
0.5 V Sensor voltage < 4.85 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.
P1750/
P0105
H
Sensor voltage is higher than specified
value.
• IAP sensor signal circuit is open or shorted to
VCC or ground circuit open.
• IAP sensor signal circuit is shorted to ground or
VCC circuit open.
L
Sensor voltage is lower than specified
value.
When using the multi circuit tester, do not strongly touch the terminal of the ECM coupler with
a needle-point tester probe to prevent terminal damage.
