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.
If no pulse signal is transmitted by the camshaft position sensor (for intake camshaft) despite the camshaft rotating, the ECM interprets this as a malfunction of the sensor.
