P0235 TC BOOST SENSOR

Description

INFOID:0000000001090439

The turbocharger boost sensor detects pressure in the exit side of the charge air cooler. The sensor output
voltage to the ECM increases as pressure increases.

DTC Logic

INFOID:0000000001115075

DTC DETECTION LOGIC

NOTE:
• If DTC P0235 is displayed with DTC P0651, first perform trouble diagnosis for DTC P0651. Refer to

EC-1395, "DTC Logic"

.

• Conditions for applying the diagnostic procedure to the stored DTCs:

The DTC is declared present after the ignition has been switched on for 1 second, with a warm engine when
the vehicle is stationary.

• If the DTC is present:
- Malfunction indicator (Red) lights up.

Diagnosis Procedure

INFOID:0000000001089850

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

 Check ground connection E17. Refer to Ground inspection in 

GI-41, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK TUBOCHARGER BOOST SENSOR SUPPLY CIRCUIT

1.

Disconnect turbocharger boost sensor harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between turbocharger boost sensor connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

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

3.

CHECK TUBOCHARGER BOOST SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

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

2.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

DTC No.

Component Inspection

INFOID:0000000001090195

1.

CHECK TURBOCHARGER BOOST SENSOR-I

1.

Turn ignition switch OFF.

2.

Remove turbocharger boost sensor with its harness connected.

3.

Turn ignition switch ON.

4.

Select “DATA MONITOR” mode with CONSULT-III. 

5.

Check “BOOST_PRESS” and “ATOMOS_PRESS” indication. 

If the value is not very close to “ATOMOS_PRESS”, maximum pressure difference between
“ATOMOS_PRESS” and “BOOST_PRESS” with the ignition switch ON (engine stop) = 

±

 50 mbar? 

YES

>> GO TO 2.

NO

>> Replace turbocharger boost sensor.

2.

CHECK TURBOCHARGER BOOST SENSOR-II

1.

Use pump to apply turbocharger boost sensor as shown in the
figure.

2.

Apply a pressure of between 10kPa(0.100 bar, 0.102 kg/cm

2

,

1.5 psi) - 13kPa(0.130 bar, 0.133 kg/cm

2

, 1.9 psi) [maximum

pressure to be applied: 13kPa(0.130 bar, 0.133 kg/cm

2

, 1.9

psi)].

3.

Select “DATA MONITOR” mode with CONSULT-III. 

4.

Check “BOOST_PRESS” indication with that given by the vac-
uum pump.

If there is no discrepancy?

YES

>> INSPECTION END

NO

>> Replace turbocharger boost sensor.
