P0112 2008 Nissan Rogue Code - Intake Air Temperature Circuit Low Input
Quick Answer
The P0112 diagnostic trouble code (DTC) for a 2008 Nissan Rogue indicates that there is a low input signal in the intake air temperature (IAT) circuit. Common causes include Faulty IAT Sensor: The most common cause of the P0112 code is a defective or failed IAT sensor, Damaged Wiring or Connectors: Damage to the wiring or connectors in the IAT circuit can disrupt the signal between the sensor and the ECM, ECM Malfunction: A malfunctioning ECM can also trigger the P0112 code by misinterpreting the IAT sensor signal. 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 2008 Nissan Rogue Description
The P0112 diagnostic trouble code (DTC) for a 2008 Nissan Rogue indicates that there is a low input signal in the intake air temperature (IAT) circuit. The IAT sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture to optimize combustion and overall engine performance. When the ECM detects a low input signal from the IAT sensor, it may cause the engine to run inefficiently, leading to reduced fuel economy, rough idling, and potential drivability issues.
Common Causes of P0112 2008 Nissan Rogue
- Faulty IAT Sensor: The most common cause of the P0112 code is a defective or failed IAT sensor.
- Damaged Wiring or Connectors: Damage to the wiring or connectors in the IAT circuit can disrupt the signal between the sensor and the ECM.
- ECM Malfunction: A malfunctioning ECM can also trigger the P0112 code by misinterpreting the IAT sensor signal.
- Intake Air Leaks: Any leaks in the intake system can affect the IAT sensor's readings, leading to a low input signal.
- Engine Overheating: Excessive heat in the engine bay can affect the IAT sensor's accuracy, causing it to report a low temperature reading.
Symptoms of P0112 2008 Nissan Rogue
- Check Engine Light: The most common symptom associated with the P0112 code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Fuel Economy: A malfunctioning IAT sensor can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Rough Idling: Incorrect air-fuel ratios can result in rough idling or unstable engine speeds.
- Engine Stalling: In severe cases, a faulty IAT sensor can cause the engine to stall while driving or at idle.
- Reduced Power: The engine may experience reduced power output, especially during acceleration.
How to Fix P0112 2008 Nissan Rogue
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the DTC and perform a thorough inspection of the IAT sensor, wiring, and connectors.
- Replace the IAT Sensor: If the sensor is found to be faulty, replace it with a new OEM or aftermarket sensor.
- Repair Wiring or Connectors: Repair or replace any damaged wiring or connectors in the IAT circuit to ensure a secure connection.
- Clear the DTC: After completing the repair, clear the DTC using the diagnostic scan tool to reset the ECM and turn off the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the repair has resolved the issue and that the engine is running smoothly.
Cost to Fix P0112 2008 Nissan Rogue
The cost of repairing the P0112 code on a 2008 Nissan Rogue can vary depending on the specific cause of the issue and the cost of parts and labor. In general, the cost of replacing an IAT sensor ranges from $50 to $100, while repairing damaged wiring or connectors may add to the total cost. Labor rates at auto repair shops typically range from $80 to $150 per hour, so the total repair cost could range from $150 to $300 or more. It's important to consult with a trusted mechanic or dealership to get an accurate estimate based on the specific diagnosis and repair needs of your vehicle.
