DTC codes / P2Bxx · Hybrid propulsion / P2B60
The engine computer has detected that the position sensor for the coolant flow control valve is reporting a signal outside its expected range or behaving erratically, so the valve's actual position cannot be trusted. This valve regulates coolant flow to manage engine temperature, and the fault means the computer sees implausible sensor voltage or a correlation error during its self-checks.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
