On-Vehicle Inspection [10/2022 - ]: Procedure
WARNING: This page is about a different car, the 2025 Toyota Highlander, 2024 Toyota Highlander, and 2023 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT NO. 2 TURBO PRESSURE SENSOR
- Check the terminal voltage.
- Disconnect the No. 2 turbo pressure sensor connector.
- 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.

(to No. 2 Turbo Pressure Sensor)
- Check the turbo pressure.
- Turn the ignition switch to ON.
- According to the display on the GTS read the Data List.

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.
- Check the terminal voltage.
