Overall Function Check

UBS00D6Z

Use this procedure to check the overall function of the EGR temperature sensor. During this check, a 1st trip
DTC might not be confirmed.

PROCEDURE FOR MALFUNCTION B

 With GST

1.

Start engine and warm it up to normal operating temperature.

2.

Run engine at idle for at least 2 minutes.

3.

Confirm that EGR valve is not lifting.
If NG, perform trouble diagnosis for DTC P1402.
Refer to 

EC-457

 .

4.

Check voltage between ECM terminal 63 (EGR temperature
sensor signal) and ground at about 1,500 rpm with EGR valve
lifted up to the full position by hand.
Voltage should decrease to less than 1.0V.

5.

If NG, go to 

EC-297, "Diagnostic Procedure"

 .

If OK, perform trouble diagnoses for DTC P0400 and P1400.
Refer to 

EC-276

 , 

EC-451

 .

Diagnostic Procedure

UBS00D71

1. 

CHECK POWER SUPPLY

1.

Turn ignition switch OFF.

2.

Disconnect EGR temperature sensor harness connector.

3.

Turn ignition switch ON.

4.

Check voltage between terminal 1 and ground with CONSULT-II
or tester.

OK or NG

OK

>> GO TO 2.

NG

>> Repair harness or connectors.

2. 

CHECK GROUND CIRCUIT

1.

Turn ignition switch OFF.

2.

Check harness continuity between EGR temperature sensor terminal 2 and engine ground.
Refer to Wiring Diagram.

3.

Also check harness for short to power.

OK or NG

OK

>> GO TO 4.

NG

>> GO TO 3.

3. 

DETECT MALFUNCTIONING PART

Check the harness for open or short between EGR temperature sensor and ECM.

>> Repair open circuit or short to ground or short to power in harness or connector.

4. 

CHECK EGR TEMPERATURE SENSOR

Refer to 

EC-298, "Component Inspection"

 .

OK or NG

OK

>> GO TO 5.

NG

>> Replace EGR temperature sensor.

SEF345V

Voltage

: Approximately 5V

SEF263W

Continuity should exist.

5. 

CHECK INTERMITTENT INCIDENT

Perform 

EC-120, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"

 .

>> INSPECTION END.

Component Inspection

UBS00D72
