Caution / Notice / Hint
WARNING: This page is about a different car, the 2025 Lexus RX 350, 2024 Lexus RX 350, and 2023 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
- If the DTC P2182-11 or P2182-15 is output simultaneously with DTC P2182-2A, the engine coolant temperature sensor may have an open or a short circuit. Troubleshoot those DTCs first.
- When the DTC is output, check the engine coolant temperature using the GTS. Enter the following menus: Powertrain / Engine / Data List / Coolant Temperature Sensor2. If the Coolant Temperature Sensor2 value is lower than the actual engine coolant temperature (for cylinder head side), the engine coolant temperature sensor (for cylinder head side) circuit may be malfunctioning. In this case, check the wire harnesses and connectors (and those connections) between the ECM and the engine coolant temperature sensor (for cylinder head side) first.
