Component InspectionINFOID:0000000009462183
1.CHECK MASS AIR FLOW SENSOR-1
With CONSULT
1. Turn ignition switch OFF.
2. Reconnect all harness connectors disconnected.
3. Start engine and warm it up to normal operating temperature.
4. Connect CONSULT and select “DATA MONITOR” mode of “ENGINE”.
5. Select “MAS A/F SE-B1” and check indication.
*: Check for linear voltage rise in response to engine being increased to about 4,000 rpm.
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK FOR THE CAUSE OF UNEVEN AIR FL OW THROUGH MASS AIR FLOW SENSOR
1. Turn ignition switch OFF.
2. Check for the cause of uneven air flow through mass air flow sensor. Refer to the following.
- Crushed air ducts
- Malfunctioning seal of air cleaner element
- Uneven dirt of air cleaner element
- Intake valve deposits
- Improper specification of intake air system parts
Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.

DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Is it necessary to erase permanent DTC?
YES >> GO TO 3.
NO >> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-240, "Component Function Check"
.
NOTE:
Use the component function check to check the overall func tion of the IAT sensor circuit. During this check, a
1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-240, "Diagnosis Procedure"
.
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-
dure before conducti ng the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. 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
1. 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).
2. 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.
3. Start engine and let it idle for 5 minutes or more.
CAUTION:
Never turn ignition swit ch OFF during idling.
4. Check 1st trip DTC.
DTC No. CONSULT screen terms

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