P0111 2016 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 2016 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 2016 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)
How to Fix the DTC P0111 2016 Toyota RAV4?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

Frequently Asked Questions about P0111 2016 Toyota RAV4 Code
1. What does the OBDII code P0111 mean on a 2016 Toyota RAV4?
The P0111 code indicates that the Intake Air Temperature (IAT) sensor is detecting a gradient or variation in air temperature readings that exceeds the expected range.
2. What are the common symptoms of code P0111 in a 2016 Toyota RAV4?
Common symptoms include poor fuel efficiency, rough idling, difficulty starting, reduced engine performance, and an illuminated check engine light.
3. What causes the P0111 code in a 2016 Toyota RAV4?
Possible causes include a faulty IAT sensor, wiring issues such as damaged or corroded connections, intake air leaks, or issues with the engine control module (ECM).
4. Can a dirty air filter trigger the P0111 code in a 2016 Toyota RAV4?
Yes, a clogged or dirty air filter can restrict airflow and affect the IAT sensor readings, potentially triggering this code.
5. How do I diagnose code P0111 on a 2016 Toyota RAV4?
Start by inspecting the IAT sensor and its wiring for damage or corrosion. Check the air filter and intake system for blockages, and use a scan tool to monitor sensor readings for irregularities.
6. Can I drive my 2016 Toyota RAV4 with a P0111 code?
While it may be safe to drive short distances, prolonged driving with this code can lead to poor fuel efficiency and potential damage to the engine or emissions system.
7. How do I fix code P0111 on a 2016 Toyota RAV4?
Repairs may include replacing the IAT sensor, cleaning or replacing the air filter, fixing damaged wiring, or addressing intake air leaks.
8. How much does it cost to repair a P0111 code on a 2016 Toyota RAV4?
The cost can vary depending on the cause, but replacing the IAT sensor typically costs $50–$150 for parts and labor.
9. Is the Intake Air Temperature Sensor the same as the Mass Air Flow Sensor in a 2016 Toyota RAV4?
No, they are different sensors. The IAT sensor measures air temperature, while the Mass Air Flow (MAF) sensor measures the amount of air entering the engine.
10. Can a faulty ECM cause the P0111 code on a 2016 Toyota RAV4?
While rare, a malfunctioning ECM can misinterpret sensor data and trigger the P0111 code. This should be considered only after ruling out more common causes.
