2. Remove turbocharger boost sensor with its harness connector.
3. Install pressure pump (A) to turbocharger boost sensor .

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)].

Is the inspection result normal?
