P0111 2017 Toyota RAV4 Code - Intake Air Temperature Sensor Gradient Too High
Quick Answer
The Intake Air Temperature (IAT), mounted on the Mass Air Flow meter sub-assembly, monitors the intake air temperature. Common causes include Dirty air filter, Faulty Intake Air Temperature (IAT) Sensor (Part of the Mass Air Flow [MAF] Sensor), Intake Air Temperature sensor harness is open or shorted. 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 P0111 2017 Toyota RAV4 Description
The ECM performs OBD II monitoring based on the values from the intake air temperature sensor. If there is no change of the sensor value within the normal range, the ECM will not be able to perform OBD II monitoring or will misdiagnose that there is a malfunction in the sensor. The ECM detects when the intake air temperature sensor value is stuck by performing monitoring after the ignition switch is turned off or the engine is started (short soak or long soak).
What are the Possible Causes of the DTC P0111 2017 Toyota RAV4?
- Dirty air filter
- Faulty Intake Air Temperature (IAT) Sensor (Part of the Mass Air Flow [MAF] Sensor)
- Intake Air Temperature sensor harness is open or shorted
- Intake Air Temperature sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
