Code P0112 2012 Nissan Versa Description
The diagnostic trouble code (DTC) P0112 for a 2012 Nissan Versa indicates an issue with the Intake Air Temperature (IAT) sensor circuit, specifically a low input signal. The IAT sensor is responsible for monitoring the temperature of the air entering the engine intake. This data is crucial for the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance and efficiency. When the ECM detects a low input signal from the IAT sensor, it means that the temperature reading is lower than expected, which can lead to incorrect fuel and ignition adjustments.
Common Causes of P0112 2012 Nissan Versa
- Faulty Intake Air Temperature (IAT) sensor
- Damaged wiring or connectors in the IAT circuit
- Corrosion or poor connection at the sensor or ECM
- ECM malfunction
- Intake air leaks affecting sensor readings
Symptoms of P0112 2012 Nissan Versa
- Decreased fuel efficiency
- Rough idling or stalling
- Engine hesitation or rough acceleration
- Check Engine Light illuminated
How to Fix P0112 2012 Nissan Versa
- Begin by locating the IAT sensor in the intake air duct or manifold.
- Inspect the wiring and connectors for any damage, corrosion, or poor connections. Repair or replace as necessary.
- Test the IAT sensor using a multimeter to check for proper resistance values. Replace the sensor if it is out of specifications.
- Clear the DTC using a scan tool and drive the vehicle to verify that the code does not return.
- If the code persists, further diagnostic testing may be required to identify the underlying issue.
Cost to Fix P0112 2012 Nissan Versa
The cost of repairing the Intake Air Temperature Circuit Low Input issue on a 2012 Nissan Versa can vary depending on the specific cause of the problem. In general, replacing a faulty IAT sensor can range from $50 to $150, while addressing wiring or connector issues may cost around $100 to $200. Labor costs at an auto repair shop typically range from $80 to $150 per hour, and the total repair bill can add up to a few hundred dollars or more.
