WARNING: This page is about a different car, the 2024 Lexus ES 250, 2023 Lexus ES 250, 2022 Lexus ES 250, and 2021 Lexus ES 250. 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.
