Code P0113 2009 Nissan Altima Sedan Description

The P0113 code for a 2009 Nissan Altima Sedan specifically 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 optimal air-fuel mixture for combustion. When the sensor detects a high voltage input, it means that the temperature reading is higher than expected, potentially leading to incorrect fuel delivery and ignition timing.

Tech Notes for P0113 2009 Nissan Altima Sedan

Intake Air Temperature (IAT) sensor is built into the mass air flow 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.
