P0110 IAT SENSOR
DescriptionINFOID:0000000001162577
The intake air temperature sensor is built into mass air flow sensor. The sensor detects intake air temperature
and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical
resistance of the thermistor decreases in response to the temperature rise.
DTC LogicINFOID:0000000001162578
DTC DETECTION LOGIC
NOTE:
If DTC P0110 is displayed with DTC P0641, first perform trouble diagnosis for DTC P0641. Refer to
EC-1180, "
DTC Logic".
Conditions for applying the diagnostic procedure to the stored DTCs:
The DTC is declared present after the ignition has been switched on for at least 10 seconds.
Diagnosis ProcedureINFOID:0000000001162579
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Check ground connection E15. Refer to Ground inspection in GI-58, "
Circuit Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY CIRCUIT-II
1. Disconnect mass air flow sensor (with intake air temperature sensor) harness connector.
2. Turn ignition switch ON.
3. Check the voltage between mass air flow sensor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK INTAKE AIR TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between mass air flow sensor harness connector and ECM harness connector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal?
DTC No. Trouble diagnosis name Possible cause
