Monitor Description
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.
The ECM calculates the air outlet duct internal pressure from the No. 2 turbo pressure sensor output voltage. If the No. 2 turbo pressure sensor output voltage is not within the normal range, there may be a malfunction in the No. 2 turbo pressure sensor or an open or short circuit. The ECM illuminates the MIL and stores a DTC.
Example:
When the sensor output voltage is higher than 4.9 V for 3 seconds or more, the ECM stores a DTC.
