Code P0112 2006 Nissan Pathfinder Description

The P0112 code for a 2006 Nissan Pathfinder indicates a problem with the Intake Air Temperature (IAT) sensor circuit, specifically a low input signal. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion. When the ECU receives a low input signal from the IAT sensor, it may not be able to accurately adjust the mixture, leading to issues with engine performance, fuel efficiency, and emissions.

Tech Notes for P0112 2006 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 low voltage from the sensor is sent to ECM.
