P014E GMC 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.

What it means: P014E GMC indicates Oxygen Sensor Slow Response Rich To Lean Bank 2 sensor 1.
Common causes: 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: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P014E GMC Description

The Powertrain Control Module (PCM) continuously monitors the Heated Oxygen Sensor (HO2S) activity for 100 seconds. During the monitor period the PCM counts the number of times that the HO2S responds from rich to lean and from lean to rich and adds the amount of time it took to complete all transitions. With this information, the PCM can determine the average time for all transitions. If the average response time is too slow, a DTC sets.
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.
