On-Vehicle Inspection [02/2024 - ]: Procedure

  1. INSPECT NO. 1 TURBO PRESSURE SENSOR 
    1. Check the terminal voltage.
      1. Disconnect the No. 1 turbo pressure sensor connector.
      2. Measure the voltage according to the value(s) in the table below.

        Standard Voltage

        Tester Connection Condition Specified Condition
        A19-3 (VC) - A19-1 (E2) Ignition switch ON 4.5 to 5.5 V

        *a Front view of wire harness connector
        (to No. 1 Turbo Pressure Sensor)
      3. If the result is not as specified, repair or replace the wire harness or connector.
    2. Check the turbo pressure.
      1. Turn the ignition switch to ON.
      2. According to the display on the GTS read the Data List.

        OK

        The value is approximately equal to atmospheric pressure.

        HINT: 

        • Standard atmospheric pressure is approximately 101 kPa (abs) (15 psi (abs)).
        • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies by weather.
      3. Connect the No. 1 turbo pressure sensor connector.
