P014E Cadillac Code - Oxygen Sensor Slow Response Rich To Lean Bank 2 sensor 1
Quick Answer
The Powertrain Control Module (PCM) continuously monitors the Heated Oxygen Sensor (HO2S) activity for 100 seconds. Common causes include Faulty Heated Oxygen Bank 2 Sensor 1, Heated Oxygen Bank 2 Sensor 1 harness is open or shorted, Heated Oxygen Bank 2 Sensor 1 circuit poor electrical connection. 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.

Code P014E Cadillac Description
The PCM determines the lean to rich transition when the HO2S voltage changes from less than 300 mV to greater than 600 mV. The PCM determines the rich to lean transition when the HO2S voltage changes from more than 600 mV to less than 300 mV. An HO2S that responds too slowly is most likely defective.
