P013D 2016 Chevrolet Silverado Code - HO2S Slow Response Lean to Rich Bank 2 Sensor 2
Quick Answer
The Heated Oxygen Sensors (HO2S) are used for fuel control and catalyst monitoring. Common causes include Faulty Heated Oxygen Bank 2 Sensor 2, Heated Oxygen Bank 2 Sensor 2 harness is open or shorted, Heated Oxygen Bank 2 Sensor 2 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 P013D 2016 Chevrolet Silverado Description
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed Loop earlier and the ECM to calculate the air-to-fuel ratio sooner.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the accumulated mass airflow monitored during lean-to-rich transitions between 350 - 650 mV is greater than calibrated value.
What are the Possible Causes of the DTC P013D 2016 Chevrolet Silverado?
- Faulty Heated Oxygen Bank 2 Sensor 2
- Heated Oxygen Bank 2 Sensor 2 harness is open or shorted
- Heated Oxygen Bank 2 Sensor 2 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
- Engine vacuum leaks
How to Fix the DTC P013D 2016 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P013D 2016 Chevrolet Silverado Code
1. What does the OBDII code P013D mean for a 2016 Chevrolet Silverado?
P013D indicates that the downstream oxygen sensor (Bank 2, Sensor 2) is slow to respond during transitions from a lean to rich air-fuel mixture.
2. What are the common symptoms of P013D in a 2016 Chevrolet Silverado?
Symptoms may include the check engine light turning on, poor fuel efficiency, failed emissions tests, and possible engine performance issues.
3. What causes the P013D code to appear?
Common causes include a faulty downstream oxygen sensor, exhaust leaks, wiring or connector issues, or a defective catalytic converter.
4. Is it safe to drive my 2016 Chevrolet Silverado with the P013D code?
While it may be safe to drive in the short term, prolonged driving with this issue could lead to poor fuel economy and potential damage to the catalytic converter.
5. How do I fix the P013D code on my 2016 Chevrolet Silverado?
Repairs may involve replacing the Bank 2 Sensor 2 oxygen sensor, fixing exhaust leaks, inspecting and repairing wiring or connectors, or replacing the catalytic converter if it has failed.
6. How can I diagnose the P013D code in my Silverado?
Use an OBDII scanner to confirm the code, inspect the oxygen sensor for damage, check for exhaust leaks or wiring issues, and verify the catalytic converter's condition.
7. What is Bank 2 Sensor 2 in my 2016 Chevrolet Silverado?
Bank 2 refers to the side of the engine opposite Cylinder 1, and Sensor 2 is the downstream oxygen sensor located after the catalytic converter.
8. Can a dirty air filter cause the P013D code?
A dirty air filter is unlikely to directly cause this code, but it can contribute to air-fuel ratio issues if the engine is not receiving adequate airflow.
9. How much does it cost to repair the P013D code on a 2016 Chevrolet Silverado?
Replacing the oxygen sensor typically costs $150–$300, including parts and labor. Additional repairs, like fixing exhaust leaks or replacing the catalytic converter, may increase the cost.
10. How can I prevent the P013D code from returning?
Regular maintenance, such as inspecting the exhaust system, replacing oxygen sensors as needed, and ensuring proper engine performance, can help prevent the code from reoccurring.
