- Turn ignition switch OFF.
- Remove turbocharger boost sensor with its harness connector.
- Install pressure pump (A) to turbocharger boost sensor (1).

- Turn ignition switch ON.
- Check the voltage between ECM harness connector terminals under 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)].
