Turbo Boost Sensor: Testing and Inspection

COMPONENT INSPECTION
Turbocharger boost sensor
1. Remove hose from sensor.




2. Turn ignition switch "ON" and check output voltage between terminal (2) and engine ground.
The voltage should be 1.9 to 3.0 V.
3. Apply air pressure of +40.0 kPa (300 mm Hg, 11.81 inHg, 5.80 psi) to turbocharger boost sensor as shown in figure and check the output voltage.
The voltage should be 0.6 to 1.0 V higher than the value measured in step 2.
4. If NG, replace turbocharger boost sensor.

CAUTION:
- Always calibrate the pressure gauge when using it.
- Inspection should be done at room temperature [10 - 30°C (50 - 86°F).
