Code P0112 2006 Nissan Altima Sedan Description
The P0112 diagnostic trouble code (DTC) for a 2006 Nissan Altima Sedan indicates that there is a low input signal in the intake air temperature (IAT) sensor circuit. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for determining the proper air/fuel mixture for combustion. When the PCM (powertrain control module) detects that the input signal from the IAT sensor is lower than expected, it triggers the P0112 code. This can lead to issues with fuel efficiency, emissions, and overall engine performance.
Common Causes of P0112 2006 Nissan Altima Sedan
- Faulty IAT sensor
- Damaged wiring or connectors in the sensor circuit
- Malfunctioning PCM
- Air intake system issues
- Electrical issues in the sensor circuit
Symptoms of P0112 2006 Nissan Altima Sedan
- Decreased fuel efficiency
- Rough idling or stalling
- Check Engine Light illuminated
- Engine running too rich or too lean
- Poor acceleration or overall performance
How to Fix P0112 2006 Nissan Altima Sedan
- Begin by visually inspecting the IAT sensor, wiring, and connectors for any signs of damage or corrosion.
