P014C Code - Oxygen Sensor Slow Response Rich to Lean Bank 1 Sensor 1

Quick Answer

The Powertrain Control Module (PCM) or Engine Control Module (ECM) continuously monitors the Heated Oxygen Sensor (HO2S) activity. Common causes include Faulty Heated Oxygen Bank 1 Sensor 1, Heated Oxygen Bank 1 Sensor 1 harness is open or shorted, Heated Oxygen Bank 1 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 P014C Description

The Powertrain Control Module (PCM) or Engine Control Module (ECM) continuously monitors the Heated Oxygen Sensor (HO2S) activity. During the monitor period the PCM/ECM 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/ECM can determine the average time for all transitions. If the average response time is too slow, a DTC sets.
