DTC P00B1-11: Radiator Coolant Temperature Sensor Circuit Short to Ground [10/2022 - ]: Description

WARNING: This page is about a different car, the 2025 Lexus RX 450h+, 2025 Lexus RX 350h, 2024 Lexus RX 450h+, 2024 Lexus RX 350h, and 2023 Lexus RX 350h. However, it is still accessible from the selected car via links, so may be relevant.

The No. 2 engine coolant temperature sensor is installed to the radiator pipe between the engine and radiator and monitors the thermostat operation.

The structure of the thermistor used in the No. 2 engine coolant temperature sensor and its connection to the ECM are the same as those of the intake air temperature sensor.

Refer to DTC P0110-11.

Refer to DESCRIPTION [10/2022 - 08/2023] , or refer to DTC P0110-11: Intake Air Temperature Sensor 1 Bank 1 Circuit Short to Ground [08/2023 - ]

HINT:

When this DTC is output, check the No. 2 engine coolant temperature in the Data List. Enter the following menus: Powertrain / Engine / Data List / Radiator Coolant Temperature.

DTC No.	Radiator Coolant Temperature	Malfunction
P00B1-11	Higher than 135°C (275°F)	Short to ground in THTW circuit

If the Data List values are normal, it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

Refer to CHECK FOR INTERMITTENT PROBLEMS [10/2022 - ]
