P0114 Buick Code - Intake Air Temperature Circuit Intermittent
Quick Answer
The P0114 Buick code indicates a problem with the Intake Air Temperature (IAT) Circuit being intermittent. Common causes include Faulty IAT Sensor: The Intake Air Temperature sensor itself may be malfunctioning, sending erratic signals to the ECM, Loose or Corroded Wiring: Loose or corroded wiring connections between the IAT sensor and the ECM can cause intermittent signal interruptions, ECM Malfunction: A malfunctioning Engine Control Module 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 P0114 Buick Description
The P0114 Buick code indicates a problem with the Intake Air Temperature (IAT) Circuit being intermittent. The Intake Air Temperature 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 ECM detects an intermittent issue with the IAT circuit, it means that there is a sporadic interruption in the sensor's signal, which can lead to incorrect air/fuel mixture, affecting engine performance.
Common Causes of P0114 Buick
- Faulty IAT Sensor: The Intake Air Temperature sensor itself may be malfunctioning, sending erratic signals to the ECM.
- Loose or Corroded Wiring: Loose or corroded wiring connections between the IAT sensor and the ECM can cause intermittent signal interruptions.
- ECM Malfunction: A malfunctioning Engine Control Module may not be able to interpret the signals from the IAT sensor correctly.
- Air Filter Contamination: A clogged or dirty air filter can affect the IAT sensor's readings, leading to an intermittent circuit issue.
Symptoms of P0114 Buick
- Check Engine Light: The most common symptom associated with the P0114 code is the illumination of the Check Engine Light on the dashboard.
- Engine Performance Issues: The vehicle may experience rough idling, hesitation during acceleration, or a decrease in overall engine performance.
- Poor Fuel Efficiency: Incorrect air/fuel mixture due to the IAT circuit issue can lead to decreased fuel efficiency.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting due to the intermittent IAT circuit problem.
How to Fix P0114 Buick
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific error code and perform a thorough inspection of the IAT sensor and its wiring.
- Replace the IAT Sensor: If the sensor is found to be faulty, replace it with a new one and ensure proper installation.
- Check Wiring Connections: Inspect the wiring connections for any signs of damage, corrosion, or looseness. Repair or replace as needed.
- Clear Error Codes: After the repair is completed, clear the error codes with a diagnostic scanner to reset the Check Engine Light.
- Test Drive: Take the vehicle for a test drive to ensure that the engine performance has improved and the issue has been resolved.
