P0114 Chevrolet Code - Intake Air Temperature Circuit Intermittent

Quick Answer

The P0114 code for Chevrolet vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit being intermittent. Common causes include Faulty IAT Sensor: The IAT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM, Damaged Wiring or Connectors: The wiring or connectors in the IAT sensor circuit may be damaged or corroded, leading to intermittent signal transmission, ECM Malfunction: A malfunctioning ECM can also cause issues with the IAT sensor circuit, as it may not be able to process the sensor data 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 P0114 Chevrolet Description

The P0114 code for Chevrolet vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit being intermittent. 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 for optimal combustion. When the IAT sensor circuit is intermittent, it means that there is a disruption in the signal being sent to the ECM, leading to potential performance issues.

Common Causes of P0114 Chevrolet

  1. Faulty IAT Sensor: The IAT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
  2. Damaged Wiring or Connectors: The wiring or connectors in the IAT sensor circuit may be damaged or corroded, leading to intermittent signal transmission.
  3. ECM Malfunction: A malfunctioning ECM can also cause issues with the IAT sensor circuit, as it may not be able to process the sensor data correctly.
  4. Intermittent Connection: Loose or poor connections in the sensor circuit can result in intermittent signal transmission to the ECM.
  5. Environmental Factors: Extreme temperatures or exposure to moisture can also affect the IAT sensor circuit's performance.

Symptoms of P0114 Chevrolet

  1. Check Engine Light: The most common symptom associated with the P0114 code is the illumination of the Check Engine Light on the vehicle's dashboard.
  2. Poor Performance: The vehicle may experience a decrease in performance, such as sluggish acceleration or rough idling.
  3. Reduced Fuel Efficiency: An intermittent IAT sensor circuit can lead to incorrect air-fuel mixture adjustments, resulting in decreased fuel efficiency.
  4. Engine Stalling: In severe cases, the engine may stall unexpectedly due to improper air-fuel mixture ratios.
  5. Increased Emissions: A faulty IAT sensor circuit can cause the vehicle to emit higher levels of pollutants due to inefficient combustion.

How to Fix P0114 Chevrolet

  1. Diagnostic Testing: Begin by using a diagnostic scanner to retrieve the trouble codes and perform testing on the IAT sensor circuit to determine the exact cause of the issue.
  2. Inspect Wiring and Connectors: Check the wiring and connectors in the IAT sensor circuit for any damage, corrosion, or loose connections. Repair or replace as necessary.
  3. Replace IAT Sensor: If the IAT sensor is found to be faulty, replace it with a new sensor to ensure accurate temperature readings.
  4. Clear Codes: After completing the repair, clear the trouble codes from the ECM memory using the diagnostic scanner.
  5. Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the Check Engine Light does not reappear.

Cost to Fix P0114 Chevrolet

The cost of repairing a P0114 code for a Chevrolet vehicle can vary depending on the specific cause of the issue and the labor rates in your area. Generally, the cost of replacing an IAT sensor can range from $50 to $150, while addressing wiring or connector issues may add to the total repair cost. The total repair cost, including parts and labor, could range from $100 to $300. Keep in mind that labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate based on your location and vehicle model.
