P0112 2016 Toyota RAV4 Code - Intake Air Temperature Circuit Low Input
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 P0112 2016 Toyota RAV4 Description
The ECM monitors the sensor voltage and uses this value to calculate the intake air temperature. When the sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the intake air temperature sensor circuit and stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0112 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 P0112 2016 Toyota RAV4?

Frequently Asked Questions about P0112 2016 Toyota RAV4 Code
What does the OBDII code P0112 mean on a 2016 Toyota RAV4?
1. The P0112 code indicates that the Intake Air Temperature (IAT) sensor is reporting a voltage signal that is too low, suggesting a potential issue with the sensor or its circuit. 2.
What are the symptoms of a P0112 code on a 2016 Toyota RAV4?
Common symptoms include poor engine performance, rough idling, reduced fuel efficiency, and possibly an illuminated Check Engine Light. 3.
What causes the P0112 code to appear on a 2016 Toyota RAV4?
Possible causes include a faulty IAT sensor, damaged wiring or connectors, a short circuit in the sensor's wiring, or a dirty air filter affecting airflow. 4.
Can a dirty air filter trigger the P0112 code?
Yes, a clogged or dirty air filter can cause restricted airflow, which may contribute to incorrect intake air temperature readings and trigger the code. 5.
How can I diagnose the P0112 code on my 2016 Toyota RAV4?
Start by inspecting the IAT sensor and its wiring for damage or corrosion. Use a multimeter to check the sensor's voltage signal and the wiring continuity. 6.
Can I drive my 2016 Toyota RAV4 with the P0112 code active?
It’s possible to drive, but it’s not recommended as the engine may run inefficiently, potentially causing further damage or higher fuel consumption. 7.
How do I fix the P0112 code on a 2016 Toyota RAV4?
Repairs may include cleaning or replacing the IAT sensor, repairing damaged wiring or connectors, replacing the air filter, or addressing any short circuits in the system. 8.
Where is the Intake Air Temperature (IAT) sensor located on a 2016 Toyota RAV4?
The IAT sensor is typically integrated into the Mass Air Flow (MAF) sensor, which is located in the air intake duct near the air filter housing. 9.
How much does it cost to repair the P0112 code on a 2016 Toyota RAV4?
Repair costs can vary, but replacing the IAT sensor generally costs $50-$200, including parts and labor, depending on the repair shop. 10.
Will clearing the P0112 code fix the problem on my 2016 Toyota RAV4?
Clearing the code will turn off the Check Engine Light temporarily, but the issue will likely recur unless the underlying problem is resolved.
