DTC P0010-13: A Camshaft Position Actuator Bank 1 Circuit Open; DTC P0020-13: Camshaft Position "A" Actuator Bank 2 Circuit Open [10/2017 - ]: Description

WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 350, 2023 Lexus IS 300, and 2022 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.

The cam timing oil control solenoid assembly operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly and supply engine oil. The camshaft timing oil control valve assembly moves when the ECM applies 12 V to the cam timing oil control solenoid assembly. The ECM changes the energizing time of the cam timing oil control solenoid assembly (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.
