Decoding the P0113 Nissan Code: Causes, Symptoms, and Solutions
When your Nissan’s check engine light illuminates and you discover the P0113 code, it’s crucial to understand its implications. This OBD2 trouble code signifies an issue with the Intake Air Temperature (IAT) sensor circuit, specifically a high input signal. Let’s delve into the details of this common Nissan problem and explore effective solutions.
Understanding P0113 in Nissan Vehicles
The P0113 code emerges when the Engine Control Unit (ECU) detects an unusually high voltage from the IAT sensor. This sensor plays a vital role in your Nissan’s engine management system, providing critical data about incoming air temperature. When this sensor malfunctions, it can lead to various performance issues.
