DTC P0110 (No. 18): Intake Air Temp. (IAT) Circuit Malfunction
Wiring Diagram
DTC Detecting Condition and Possible Cause
DTC detecting condition
• Low intake air temperature (High voltage-High resistance)
or
• High intake air temperature (Low voltage-Low resistance).
NOTE
• When DTC P0105 (No. 11), P0110 (No. 18), P0115 (No. 19) and P0120 (No. 13) are indicated together, it
is possible that "ORN" circuit is open.
• Before inspecting, be sure to check that ambient temperature is higher than –40 °C (–40 °F).
DTC Confirmation Procedure
1) Clear DTC, start engine and keep it at idle for 1 min.
2) Select "DTC" mode on scan tool and check DTC.
