Demystifying Toyota P0113: A Comprehensive Guide to Diagnosis and Repair
When your Toyota’s check engine light illuminates and you discover the P0113 error code, it’s crucial to understand its implications. This diagnostic trouble code (DTC) signals an issue with the Intake Air Temperature (IAT) sensor circuit, potentially affecting your vehicle’s performance and fuel efficiency.
Understanding the P0113 Code
The P0113 code indicates that the Engine Control Module (ECM) has detected an unusually high input from the IAT sensor. This sensor plays a vital role in optimizing engine performance by measuring the temperature of incoming air. When it reports abnormally high temperatures, it can lead to various issues.
