P0112 Infiniti Code - Intake Air Temperature Circuit Low Input
Quick Answer
The P0112 Infiniti code indicates that the intake air temperature sensor circuit is reporting a low input, meaning that the signal being sent by the sensor to the engine control module (ECM) is lower than the expected range. Common causes include Faulty intake air temperature sensor, Damaged wiring or connectors in the sensor circuit, Corrosion or contamination in the sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0112 Infiniti Description
The P0112 Infiniti code indicates that the intake air temperature sensor circuit is reporting a low input, meaning that the signal being sent by the sensor to the engine control module (ECM) is lower than the expected range. This sensor plays a crucial role in providing data to the ECM about the temperature of the air entering the engine. The ECM uses this information to adjust the air-fuel mixture for optimal combustion and engine performance. A malfunctioning intake air temperature sensor can lead to various issues with the vehicle's performance, fuel efficiency, and emissions.
Common Causes of P0112 Infiniti
- Faulty intake air temperature sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination in the sensor
- ECM malfunction
- Extreme temperature changes affecting sensor readings
Symptoms of P0112 Infiniti
- Decreased fuel efficiency
- Rough idling or engine stalling
- Engine misfires or hesitation
- Check Engine Light illuminated
- Reduced engine performance
How to Fix P0112 Infiniti
- Begin by locating the intake air temperature sensor, typically located near the air filter housing or intake manifold.
- Inspect the sensor and its wiring for any visible damage, corrosion, or loose connections.
- Test the sensor using a multimeter to check for proper resistance values and voltage output.
- If the sensor is faulty, replace it with a new one following manufacturer's specifications.
- Clear the error code using an OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0112 Infiniti
The typical repair costs for addressing the P0112 Infiniti code can range from $100 to $300, including the cost of a new intake air temperature sensor and labor.
