Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace error-detected parts.

3.

CHECK EXHAUST GAS TEMPERATURE SENSOR 1 CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Check exhaust gas temperature sensor 1 circuit for open and short.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

DTC No.

Component Inspection (Exhaust Gas Temperature Sensor 1)

INFOID:0000000010935741

1.

CHECK EXHAUST GAS TEMPERATURE SENSOR 1

1.

Reconnect all harness connectors disconnected.

2.

Start the engine.

3.

Select “TEMP UPSTREAM TURBINE” in “DATA MONITOR” mode of “ENGINE” with CONSULT.

4.

Maintain the following conditions for at least 2 minutes and check the monitor status “TEMP UPSTREAM
TURBINE”.

Does the value of the exhaust gas temperature sensor 1 vary?

YES

>> INSPECTION END

NO

>> Replace exhaust gas temperature sensor 1.

DTC Description

INFOID:0000000010935742

DTC DETECTION LOGIC

NOTE:
If this DTC is detected, first confirm self-diagnostic result in IPDM E/R.

POSSIBLE CAUSE

• Harness or connectors (ECM power supply circuit is open or shorted.)
• Battery
• Battery terminal
• Alternator
• IPDM E/R

FAIL-SAFE

• Mechanically activated throttle limp-home
• Torque limitation
• ESP deactivated
• Glow plug circuit deactivated
• Inhibition of idle speed control
• Factory and aftersales routines inhibited
• Freeshift Inhibited
• CCSL deactivation (considered as abnormal with dashboard message)
• Wastegate cut off
• Deactivation of the VVT

DTC CONFIRMATION PROCEDURE

1.

>> Proceed to

EC-1060, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to

GI-44, "Intermittent Incident"

.
