Monitor Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus ES 300h, 2023 Lexus ES 300h, 2022 Lexus ES 300h, 2021 Lexus ES 300h, and 2020 Lexus ES 300h. 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.
