On-Vehicle Inspection [10/2022 - ]: Procedure

2025 Toyota Highlander XLE, 4WDSECTION Procedure
  1. INSPECT NO. 2 TURBO PRESSURE SENSOR 
    1. Check the terminal voltage.
      1. Disconnect the No. 2 turbo pressure sensor connector.
      2. Measure the voltage according to the value(s) in the table below.

        Standard Voltage

        Tester Connection Condition Specified Condition
        C76-3 (VC) - C76-2 (E2) Ignition switch ON 4.5 to 5.5 V
        C76-1 (PTA) - C76-2 (E2) 3.0 to 5.5 V

        If the result is not as specified, repair or replace the wire harness or connector.

        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.

  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
