P0112 2015 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.

- 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)
