Not applicable
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following 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.
>>
GO TO 2.
PERFORM DTC CONFIRMATION PROCEDURE
-
Turn ignition switch ON and wait at least 5 seconds.
-
Check 1st trip DTC.
Is 1st trip DTC detected?
YES>>Proceed to Diagnosis Procedure.
NO>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO>>Confirmation after repair: INSPECTION END
CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY
-
Disconnect mass air flow sensor (with intake air temperature sensor) harness connector.
-
Ignition switch ON.
-
Check the voltage between mass air flow sensor harness connector and ground.
MAF sensor Ground Voltage
(Approx.)Connector Terminal F94 4 Ground Approx. 5 V
Is the inspection result normal?
YES>>GO TO 2.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
CHECK INTAKE AIR TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
-
Ignition switch OFF.
-
Disconnect ECM harness connector.
-
Check harness continuity between mass air flow sensor harness connector and ECM harness connector.
MAF sensor ECM Continuity Connector Terminal Connector Terminal F94 3 F78 40 Existed -
Also check harness for short to ground and short to power.
Is the inspection result normal?
YES>>GO TO 3.
NO>>Repair open circuit, short to ground or short to power in harness or connectors.
CHECK INTAKE AIR TEMPERATURE SENSOR
Check intake air temperature sensor. Refer to Component Inspection.
Is the inspection result normal?
YES>>Inspection End.
NO>>Replace mass air flow sensor. Refer to Removal and Installation.
CHECK INTAKE AIR TEMPERATURE SENSOR
-
Turn ignition switch OFF.
-
Disconnect mass air flow sensor harness connector and reconnect it again.
-
Turn ignition switch ON.
-
On CONSULT screen, select “ENGINE” >> “DATA MONITOR” >> “INT/A TEMP SEN”.
-
Check that the indicated value of “INT/A TEMP SEN” is almost the same as intake air temperature.
Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace mass air flow sensor. Refer to Removal and Installation.

LATCH (Lower Anchors and Tethers for CHildren) system
LATCH system lower anchor locations - bench seat
Your vehicle is equipped with special anchor points that are used with LATCH system compatible child restraints. This system may also be referred to as the ISOFIX or ISOFIX compatible system. With this system, you do not have to use a vehicle seat belt to secure the child restraint unless the combined weight of the child and child restraint exceeds 65 lbs. (29.5 kg). If the combined weight of the child and child restraint is greater than 65 lbs. (29.5 kg), use the vehicle’s seat belt (not the lower anchors) to install the child restraint. Be sure to follow the child restraint manufacturer’s instructions for installation.
