Code P0113 2012 Nissan Pathfinder Description

The P0113 diagnostic trouble code (DTC) for a 2012 Nissan Pathfinder indicates an issue with the Intake Air Temperature (IAT) sensor circuit registering a high input. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for determining the correct air-fuel mixture for combustion. When the sensor circuit detects a high voltage signal, it means that the intake air temperature is higher than normal, which can lead to various performance issues.

Tech Notes for P0113 2012 Nissan Pathfinder

Intake Air Temperature (IAT) sensor is built into the Mass Air Flow (MAF) sensor. Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.

When is the Code Detected?

- An excessively high voltage from the sensor is sent to ECM.
