P013C 2016 Chevrolet Silverado Code - HO2S Slow Response Rich to Lean 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 P013C 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 rich-to-lean transitions between 450 - 150 mV is greater than calibrated value.
What are the Possible Causes of the DTC P013C 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 P013C 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.

What does the OBDII code P013C mean for a 2016 Chevrolet Silverado?
Code P013C indicates that the oxygen sensor (HO2S) on Bank 2 Sensor 2 is detecting a slow response when transitioning from a rich to a lean air-fuel mixture.
What are the common symptoms of code P013C in a 2016 Chevrolet Silverado?
Symptoms may include an illuminated check engine light, reduced fuel efficiency, poor engine performance, and potential emissions test failure.
What causes the P013C code to occur in a 2016 Chevrolet Silverado?
Common causes include a faulty oxygen sensor, exhaust leaks near the sensor, damaged wiring or connectors, or an overly rich or lean air-fuel mixture.
Is it safe to drive a 2016 Chevrolet Silverado with a P013C code?
While the vehicle may still be drivable, ignoring the code can lead to reduced performance, poor fuel economy, and potential damage to the catalytic converter over time.
How do you fix the P013C code on a 2016 Chevrolet Silverado?
Repairs may involve replacing the Bank 2 Sensor 2 oxygen sensor, repairing wiring or connectors, addressing exhaust leaks, or resolving fuel mixture issues.
Where is the Bank 2 Sensor 2 oxygen sensor located on a 2016 Chevrolet Silverado?
Bank 2 Sensor 2 is located on the passenger side of the exhaust system, downstream of the catalytic converter.
Can a dirty air filter cause the P013C code in a 2016 Chevrolet Silverado?
A dirty air filter is unlikely to directly cause this code, but it can contribute to improper air-fuel mixture, which may affect oxygen sensor performance.
How much does it cost to repair the P013C code in a 2016 Chevrolet Silverado?
The repair cost varies but may range from $150 to $300 for an oxygen sensor replacement, depending on labor rates and sensor pricing.
Can a P013C code be caused by bad fuel quality?
Yes, poor-quality fuel can lead to incomplete combustion and an improper air-fuel ratio, which may contribute to triggering the P013C code.
Do I need to clear the P013C code after repairs on a 2016 Chevrolet Silverado?
Yes, you should clear the code with an OBDII scanner after completing repairs to ensure the issue is resolved and to reset the check engine light.
