P0113 2018 Toyota RAV4 Code - Intake Air Temperature Circuit High 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 P0113 2018 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 P0113 2018 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 P0113 2018 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.
