DTC P16B5-11: Multi Flow Control Valve Sensor Circuit Short to Ground [11/2021 - ]: Description

WARNING: This page is about a different car, the 2025 Lexus NX 350, 2024 Lexus NX 350, 2023 Lexus NX 350, and 2022 Lexus NX 350. However, it is still accessible from the selected car via links, so may be relevant.

The ball valve position sensor is installed at the top of the water control valve shaft and detects the ball valve position.

The ball valve position sensor is a non-contact type and uses Hall elements which can yield the magnetic field strength as an electrical signal through the Hall effect, which enables output voltage corresponding to the ball valve position to be obtained linearly.
