GO TO 2.
PERFORM DTC CONFIRMATION PROCEDURE
-
Start engine and let it idle for at least 5 seconds.
-
Check 1st trip DTC.
Is 1st trip DTC detected?
YES>>DTC Diagnosis Procedure
NO-1>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO-2>>Confirmation after repair: INSPECTION END
DTC Diagnosis Procedure
CHECK INTAKE AIR TEMPERATURE SENSOR 2 POWER SUPPLY CIRCUIT-I
-
Turn ignition switch OFF.
-
Disconnect turbocharger boost sensor harness connector.
