P0112 2008 Nissan Versa Code - Intake Air Temperature Circuit Low Input
Quick Answer
The P0112 diagnostic trouble code (DTC) for a 2008 Nissan Versa indicates that there is a low input signal from the Intake Air Temperature (IAT) sensor circuit. Common causes include Faulty IAT Sensor: The IAT sensor itself may be malfunctioning and providing inaccurate temperature readings, Damaged Wiring or Connectors: The wiring or connectors in the IAT sensor circuit may be damaged, leading to a low input signal, ECM Malfunction: A malfunctioning ECM may not be able to interpret the signals from the IAT sensor correctly. 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 Versa Description
The P0112 diagnostic trouble code (DTC) for a 2008 Nissan Versa indicates that there is a low input signal from the Intake Air Temperature (IAT) sensor 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 and ignition timing to optimize engine performance and fuel efficiency.
Common Causes of P0112 2008 Nissan Versa
- Faulty IAT Sensor: The IAT sensor itself may be malfunctioning and providing inaccurate temperature readings.
- Damaged Wiring or Connectors: The wiring or connectors in the IAT sensor circuit may be damaged, leading to a low input signal.
- ECM Malfunction: A malfunctioning ECM may not be able to interpret the signals from the IAT sensor correctly.
- Intake Air Leaks: Any leaks in the intake system can affect the air temperature readings and trigger this code.
- Poor Electrical Ground: A poor electrical ground in the sensor circuit can also cause a low input signal.
Symptoms of P0112 2008 Nissan Versa
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Poor Fuel Efficiency: A malfunctioning IAT sensor can lead to incorrect air-fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idling: Incorrect air temperature readings can cause the engine to idle roughly or inconsistently.
- Engine Stalling: In severe cases, the engine may stall due to incorrect air-fuel mixture adjustments.
- Reduced Engine Performance: The vehicle may experience a decrease in overall engine performance, such as sluggish acceleration or lack of power.
How to Fix P0112 2008 Nissan Versa
- Diagnose the Issue: Use a 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 faulty, replace it with a new one following the manufacturer's guidelines.
- Repair Wiring or Connectors: Repair any damaged wiring or connectors in the IAT sensor circuit.
- Check ECM Functionality: Verify the ECM's functionality and replace it if necessary.
- Clear DTCs: Clear the DTC using a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0112 2008 Nissan Versa
The typical repair costs for addressing a P0112 code on a 2008 Nissan Versa can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor in your area. It's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate. Additionally, factors such as the vehicle's make and model, as well as the engine type, can also impact the overall repair costs.
