P011B 2017 Toyota RAV4 Code - Engine Coolant Temperature/Intake Air Temperature Correlation
Quick Answer
The engine has two temperature sensors, an Engine Coolant Temperature (ECT) sensor and an Intake Air Temperature (IAT) sensor, to detect the temperature while the engine is in operation. Common causes include Faulty Engine Coolant Temperature (ECT) sensor, Engine Coolant Temperature sensor harness is open or shorted, Engine Coolant Temperature sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P011B 2017 Toyota RAV4 Description
The ECM monitors the difference between the engine coolant temperature and the intake air temperature when the engine is started cold to accurately detect the engine temperature conditions. The monitor runs when the engine is started after 7 hours or more have elapsed since the engine was stopped (ignition switch turned off) on the previous trip. If the difference between the engine coolant temperature and the intake air temperature on a cold start exceeds 25°C (45°F), the ECM interprets this as a malfunction in the engine coolant temperature sensor circuit and intake air temperature sensor circuit and stores the Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P011B 2017 Toyota RAV4?
- Faulty Engine Coolant Temperature (ECT) sensor
- Engine Coolant Temperature sensor harness is open or shorted
- Engine Coolant Temperature sensor circuit poor electrical connection
- Faulty Intake Air Temperature (IAT) sensor
- Intake Air Temperature sensor harness is open or shorted
- Intake Air Temperature sensor circuit poor electrical connection
