Code P0112 2005 Infiniti G35 Description
The P0112 code in a 2005 Infiniti G35 indicates a problem with the Intake Air Temperature (IAT) sensor circuit, specifically a low input signal. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion. When the ECU receives a low input signal from the IAT sensor, it may not be able to accurately adjust the air-fuel mixture, leading to potential performance issues.
Common Causes of P0112 2005 Infiniti G35
- Faulty IAT sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination in the sensor
- ECU malfunction
- Intake air leaks
Symptoms of P0112 2005 Infiniti G35
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation during acceleration
- Check Engine Light illuminated
- Increased emissions
How to Fix P0112 2005 Infiniti G35
- Begin by locating the IAT sensor in the intake system.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion.
- Test the IAT sensor using a multimeter to check for proper resistance values.
- Replace the IAT sensor if it is found to be faulty.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0112 2005 Infiniti G35
The typical repair costs for addressing a P0112 code in a 2005 Infiniti G35 can range from $100 to $300, depending on the specific cause of the issue and the cost of the replacement parts. This estimate includes the cost of the IAT sensor, any necessary wiring repairs, and labor charges. It's important to note that the actual costs may vary based on the location, the auto repair shop's labor rates, and the availability of parts.
