P014B Buick Code - HO2S Delayed Response Lean to Rich Bank 2 Sensor 2
Quick Answer
The P014B diagnostic trouble code (DTC) for Buick vehicles refers to a delayed response from the bank 2 sensor 2 heated oxygen sensor (HO2S) as it transitions from a lean to rich air/fuel mixture. Common causes include Faulty bank 2 sensor 2 HO2S, Wiring or connector issues, Exhaust leaks near the sensor. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
