Monitor Description
WARNING: This page is about a different car, the 2025 Lexus NX 250, 2024 Lexus NX 250, 2023 Lexus NX 250, and 2022 Lexus NX 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.
