Code P0112 2014 Chevrolet Silverado Description

The intake air temperature (IAT) sensor 1 is a variable resistor that measures the temperature of the air in the sensor bore. The Engine Control Module (ECM) supplies 5 V to the IAT sensor 1 signal circuit and a ground for the IAT sensor 1 low reference circuit. The signal varies with inlet air temperature and is displayed by the scan tool as °C (°F). The multifunction intake air sensor houses the IAT sensor 1, IAT sensor 2, Humidity sensor, Mass Air Flow (MAF) sensor and BARO pressure sensor. The Diagnostic Trouble Code (DTC) ECM detects that the IAT sensor 1 signal is warmer than 149°C (300°F) for greater than 5 s.

Frequently Asked Questions about P0112 2014 Chevrolet Silverado Code

1. What does the OBDII code P0112 mean on a 2014 Chevrolet Silverado?

P0112 indicates that the Intake Air Temperature (IAT) sensor circuit is reporting a low voltage signal, suggesting the sensor is detecting a temperature that is too low or there is an electrical issue.

2. What are the common symptoms of the P0112 code on a 2014 Chevrolet Silverado?

Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, difficulty starting, and the check engine light being illuminated.

3. What causes the P0112 code to appear in a 2014 Chevrolet Silverado?

Common causes include a faulty IAT sensor, damaged or corroded wiring, a short circuit, a dirty air filter, or a problem with the engine control module (ECM).

4. Can I drive my 2014 Chevrolet Silverado with the P0112 code?

While the vehicle may still be drivable, continued operation with this code can lead to poor performance and potential damage to the engine, so it’s best to address it promptly.

5. How do I fix the P0112 code on my 2014 Chevrolet Silverado?

Repairs may involve replacing the IAT sensor, cleaning or replacing the air filter, repairing damaged wiring, or inspecting and fixing any electrical connections in the circuit.

6. Where is the Intake Air Temperature (IAT) sensor located on a 2014 Chevrolet Silverado?

The IAT sensor is typically located in the air intake duct, near the air filter housing, or integrated with the mass air flow (MAF) sensor.

7. How much does it cost to repair the P0112 code on a 2014 Chevrolet Silverado?

Repair costs vary but typically range from $50 to $200, depending on whether the IAT sensor needs replacement or if wiring repairs are required.

8. Can a dirty air filter cause the P0112 code on a 2014 Chevrolet Silverado?

Yes, a dirty or clogged air filter can restrict airflow and affect the IAT sensor readings, potentially triggering the P0112 code.

9. How can I test the IAT sensor on my 2014 Chevrolet Silverado?

You can test the IAT sensor using a multimeter to check its resistance at different temperatures or verify the voltage signal it sends to the ECM.

10. Will clearing the P0112 code fix the issue on my 2014 Chevrolet Silverado?

Clearing the code may temporarily turn off the check engine light, but if the underlying issue isn’t resolved, the code will return.
