Monitor Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
These DTCs are designed to detect an open or short in the cam timing oil control solenoid assembly (for exhaust camshaft) circuit. If the cam timing oil control solenoid duty-cycle is excessively high or low while the power switch is on (IG) or the engine is running, the ECM will illuminate the MIL and store this DTC.
