DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING 

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting 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.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE 

1. Turn ignition switch ON and wait at least 5 seconds.

2. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-938, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012198437

1.

CHECK TURBOCHARGER BOOST SENSOR POWER SUPPLY

1. Disconnect turbocharger boost sensor harness connector.

2. Turn ignition switch ON.

3. Check the voltage between turbocharger boost sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK SENSOR POWER SUPPLY 2 CIRCUIT

Perform 

EC-1240, "Diagnosis Procedure"

.

Is inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO

>> Repair or replace error-detected parts.

3.

CHECK TURBOCHARGER BOOST SENSOR GROUND CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

DTC No.

Trouble diagnosis name

DTC detecting condition

Possible cause

P0237

TC BOOST SEN/CIRC-B1
(Turbocharger boost sensor circuit 
low input)

An excessively low voltage from the 
turbocharger boost sensor is sent to 
ECM.

• Harness or connectors

(Turbocharger boost sensor circuit is 
open or shorted.)

• Turbocharger boost sensor
• Sensor power supply 2 circuit

P0238

TC BOOST SEN/CIRC-B1
(Turbocharger boost sensor circuit 
high input)

An excessively high voltage from 
the turbocharger boost sensor is 
sent to ECM.

3. Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.

4. Also check harness for short to power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK TURBOCHARGER BOOST SENSOR INPUT SIGNAL CIRCUIT

1. Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.

2. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace error-detected parts.

5.

CHECK TURBOCHARGER BOOST SENSOR

Check the turbocharger boost sensor. Refer to 

EC-939, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Replace turbocharger boost sensor. Refer to 

EM-194, "Exploded View"

.

Component Inspection

INFOID:0000000012198438

1.

CHECK TURBOCHARGER BOOST SENSOR 

1. Turn ignition switch OFF.

2. Remove turbocharger boost sensor with its harness connector.

3. Install pressure pump (A) to turbocharger boost sensor (1).

CAUTION:

When insert a pressure pump hose to the sensor, be careful

to the damage of the sensor housing.

4. Turn ignition switch ON.

5. Check the voltage between ECM harness connector terminals

as per the following conditions.

NOTE:

• Always calibrate the pressure pump gauge when using it.

• Inspection should be done at room temperature [10 - 30

°C (50 - 86°F)].
