DTC Description

DTC DETECTION LOGIC

DTC No.	CONSULT screen terms (Trouble diagnosis content)	DTC detecting condition
P0111	IAT SENSOR 1 B1 (Intake air temperature sensor 1 circuit range/performance bank 1)	The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor, FTT sensor, and EOT sensor) shows that the voltage signal of the IAT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state.

POSSIBLE CAUSE

Harness or connectors (High or low resistance in the IAT sensor circuit)
IAT sensor

FAIL-SAFE

Not applicable

DTC CONFIRMATION PROCEDURE

1.INSPECTION START

Is it necessary to erase permanent DTC? YES >> GO TO 3.

NO >> GO TO 2.

2.CHECK INTAKE AIR TEMPERATURE (IAT) SENSOR

Turn ignition switch OFF.
Disconnect mass air flow sensor harness connector and reconnect it again.
Turn ignition switch ON.
Select “DATA MONITOR” mode with CONSULT.
Check that “INT/A TEMP SEN” indicates as per following condition.

Monitor item	Condition		Value (Approx.)
INT/A TEMP SEN	Temperature [°C (°F)]	25 (77)	1.9 - 2.1 (V)

Is the inspection result normal? YES >> GO TO 5.

NO >> Proceed to EC-207, "Diagnosis Procedure".

3.PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.

Turn ignition switch OFF and wait at least 10 seconds.
Turn ignition switch ON.
Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

Before performing the following procedure, do not add fuel.
Before performing the following procedure, check that fuel level is between 1/4 and 4/4.
Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 4.

4.PERFORM DTC CONFIRMATION PROCEDURE

Move the vehicle to a cool place.

NOTE: Cool the vehicle in an environment of ambient air temperature between −10°C (14°F) and 35°C (95°F).

Turn ignition switch OFF and leave the vehicle for 12 hours.
CAUTION: Never turn ignition switch ON during this procedure.
NOTE: The vehicle must be cooled with the food open.
Start engine and let it idle for 5 minutes or more.
CAUTION: Never turn ignition switch OFF during idling.
Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-207, "Diagnosis Procedure".

NO >> INSPECTION END 5.CHECK INTERMITTENT INCIDENT Refer to GI-41, "Intermittent Incident".

>> INSPECTION END

Diagnosis Procedure

1.CHECK INTAKE AIR TEMPERATURE (IAT) SENSOR

Check intake air temperature sensor. Refer toEC-207, "Component Inspection".

Is the inspection result normal? YES >> GO TO 2.

NO >> Replace mass air flow sensor (with intake air temperature sensor). Refer to EM-24, "Exploded View".

2.CHECK INTERMITTENT INCIDENT

Refer to GI-41, "Intermittent Incident".

>> INSPECTION END

Component Inspection

1.CHECK INTAKE AIR TEMPERATURE SENSOR
