P014E 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.
