Monitor Description
WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
This DTC is designed to detect an open or short in the camshaft timing oil control valve assembly (for intake side) circuit. If the oil control valve duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.
