P013D 2016 GMC Sierra Code - HO2S Slow Response Lean to Rich Bank 2 Sensor 2
Quick Answer
The diagnostic trouble code P013D for a 2016 GMC Sierra indicates a slow response from the downstream oxygen sensor (HO2S) located on Bank 2 Sensor 2, signaling a lean to rich air/fuel mixture. Common causes include Faulty oxygen sensor, 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 2016 GMC Sierra Description
The diagnostic trouble code P013D for a 2016 GMC Sierra indicates a slow response from the downstream oxygen sensor (HO2S) located on Bank 2 Sensor 2, signaling a lean to rich air/fuel mixture. The oxygen sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air/fuel ratio for optimal combustion. When the sensor's response time is slow, it can lead to incorrect fuel trim adjustments, affecting the engine's performance and emissions.
Common Causes of P013D 2016 GMC Sierra
- Faulty oxygen sensor
- Wiring or connector issues
- Exhaust leaks
- Vacuum leaks
- Malfunctioning ECM
Symptoms of P013D 2016 GMC Sierra
- Decreased fuel efficiency
- Reduced engine power
- Rough idling
- Hesitation during acceleration
- Increased emissions
How to Fix P013D 2016 GMC Sierra
- Begin by conducting a visual inspection of the oxygen sensor, wiring, and connectors for any signs of damage or corrosion.
- Use a scan tool to monitor the oxygen sensor's response time and check for any related trouble codes.
- Test the oxygen sensor's voltage output and response time using a multimeter to determine if it is functioning correctly.
- If the oxygen sensor is faulty, replace it with a new sensor following the manufacturer's specifications.
- Clear the trouble codes and perform a test drive to ensure the issue has been resolved.
Cost to Fix P013D 2016 GMC Sierra
The typical repair costs for addressing a HO2S slow response lean to rich Bank 2 Sensor 2 code can range from $150 to $300, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's recommended to inquire about local rates for a more accurate estimate.

Frequently Asked Questions about P013D 2016 GMC Sierra Code
1. What does the OBDII code P013D mean for a 2016 GMC Sierra?
P013D indicates "HO2S Slow Response Lean to Rich Bank 2 Sensor 2," meaning the oxygen sensor on bank 2 (downstream sensor) is taking too long to switch from a lean to rich condition.
2. What are common symptoms of the P013D code on a 2016 GMC Sierra?
Symptoms may include the check engine light turning on, decreased fuel efficiency, rough idling, or failed emissions tests.
3. What causes the P013D code to appear?
Common causes include a failing oxygen sensor, exhaust leaks, wiring or connector issues, or an inefficient catalytic converter.
4. Which oxygen sensor is affected by the P013D code?
The code refers to the downstream oxygen sensor (Sensor 2) on bank 2 of the engine, which monitors the catalytic converter's performance.
5. Can a dirty or faulty catalytic converter trigger the P013D code?
Yes, a degraded catalytic converter can cause improper exhaust flow, leading to delayed sensor response and triggering the P013D code.
6. How do you diagnose the P013D code on a 2016 GMC Sierra?
Start by inspecting the oxygen sensor wiring and connector for damage. Use a scan tool to monitor the sensor's response time and check for exhaust leaks before replacing components.
7. Can an exhaust leak cause the P013D code?
Yes, an exhaust leak upstream of the oxygen sensor can disrupt its readings and cause slow response times, triggering the code.
8. What is the most common fix for the P013D code?
The most common fix is replacing the downstream oxygen sensor on bank 2, though repairs may also involve fixing wiring, exhaust leaks, or replacing the catalytic converter.
9. Is it safe to drive with the P013D code on a 2016 GMC Sierra?
Driving with this code is generally safe in the short term, but prolonged issues can cause further damage, reduced fuel efficiency, and emissions problems.
10. How much does it cost to repair the P013D code on a 2016 GMC Sierra?
The cost varies depending on the cause, but replacing the oxygen sensor typically costs $150–$300, while catalytic converter repairs can be significantly higher.
