On-Vehicle Inspection [10/2015 - ]: Procedure

  1. INSPECT NO. 2 TURBO PRESSURE SENSOR 
    1. Remove the No. 2 turbo pressure sensor.

      See step  2

    2. Connect the No. 2 turbo pressure sensor connector.
    3. Connect the Techstream to the DLC3.
    4. Turn the engine switch on (IG) (do not start the engine).
    5. Turn the Techstream on.
    6. Enter the following menus: Powertrain / Engine / Data List / Boost Pressure Sensor.

      Powertrain > Engine > Data List 

      Tester Display
      Boost Pressure Sensor
    7. Read the value of the Data List item "Boost Pressure Sensor".

      HINT: 

      • Standard atmospheric pressure is approximately 101 kPa (abs) (15 psi (abs)).
      • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops with the approximately 1 kPa (0.1 psi). This varies with the weather.
    8. Connect a vacuum pump to the No. 2 turbo pressure sensor.

    9. Read the values in the Data List when applying vacuum and pressure to the No. 2 turbo pressure sensor using the vacuum pump.

      OK

      The values indicate on the vacuum pump when applying vaccum and pressure and the values Data List are nearly the same.

      NOTE:
      • Do not apply a pressure of 50 kPa (0.5 kgf/cm2 , 7.3 psi) or more to the No. 2 turbo pressure sensor.
      • Do not apply a vacuum of 50 kPa (0.5 kgf/cm2 , 7.3 psi) or more to the No. 2 turbo pressure sensor.

      HINT: 

      The pressure value displayed in the Data List is the pressure value indicated on the vacuum pump with the air pressure value added.

      EXAMPLE:

      Vacuum Pump Pressure Value Air Pressure Value Equation Data List Value
      Vacuum of 30 kPa (0.3 kgf/cm2 , 4.4 psi) applied 100 kPa (1.0 kgf/cm2 , 15 psi) -30 + 100 = 70 70 kPa (0.7 kgf/cm2 , 10.2 psi)
      Pressure of 30 kPa (0.3 kgf/cm2 , 4.4 psi) applied 30 + 100 = 130 130 kPa (1.3 kgf/cm2 , 19 psi)
    10. Install the No. 2 turbo pressure sensor.
