P013D Pontiac Code - HO2S Slow Response Lean to Rich Bank 2 Sensor 2

Quick Answer

The P013D diagnostic trouble code (DTC) for Pontiac vehicles indicates a slow response from the heated oxygen sensor (HO2S) located in bank 2, sensor 2. Common causes include Faulty HO2S in bank 2, sensor 2, Wiring or connector issues, Exhaust leaks. 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 P013D Pontiac Description

The P013D diagnostic trouble code (DTC) for Pontiac vehicles indicates a slow response from the heated oxygen sensor (HO2S) located in bank 2, sensor 2. This sensor is responsible for monitoring the oxygen levels in the exhaust gases after they have passed through the catalytic converter. The code specifically points to a lean to rich condition, meaning that the sensor is taking longer than expected to switch from a lean (high oxygen) to a rich (low oxygen) state. This can lead to an imbalance in the air-fuel mixture, potentially causing drivability issues and increased emissions.
