P0112

DTC P0112 INTAKE AIR TEMPERATURE (IAT) CIRCUIT LOW INPUT





WIRING DIAGRAM

CIRCUIT DESCRIPTION
Located on the air cleaner hose, this sensor constantly measures the temperature of the air entering there and converts a change in the air temperature into that in resistance through its thermistor. That is, as air temperature lowers, resistance increases and as it rises, resistance decreases. As air density of the intake air varies with variation in temperature, ECM, by monitoring the resistance, adjusts the amount of fuel injection according to the air temperature.





DETECTING CONDITION

DTC CONFIRMATION PROCEDURE
1) Clear DTC, start engine and keep it at idle for 1 mm.
2) Select "DTC" mode on scan tool and check DTC.
