P013C 2015 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 2015 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 2015 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 2015 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 P013C 2015 Chevrolet Silverado Code
What does the OBDII code P013C mean for a 2015 Chevrolet Silverado?
P013C indicates that the oxygen sensor (HO2S) on Bank 2, Sensor 2, is responding too slowly when transitioning from a rich to a lean condition, as detected by the engine control module (ECM).
What are the symptoms of code P013C in a 2015 Chevrolet Silverado?
Common symptoms include an illuminated check engine light, reduced fuel efficiency, possible rough idling, and sometimes difficulty passing emissions tests.
What causes the P013C code on a 2015 Chevrolet Silverado?
Potential causes include a faulty downstream oxygen sensor (Bank 2, Sensor 2), exhaust leaks, wiring issues, or contamination of the oxygen sensor by oil or coolant.
Can I continue driving my 2015 Chevrolet Silverado with a P013C code?
While the vehicle may still be drivable, ignoring the code can lead to reduced fuel efficiency and potential damage to the catalytic converter over time.
How do I diagnose the P013C code on my 2015 Chevrolet Silverado?
Start by inspecting the wiring and connections for the Bank 2, Sensor 2 oxygen sensor. Then, use a scan tool to monitor oxygen sensor voltage readings and compare response times.
What is Bank 2, Sensor 2 on a 2015 Chevrolet Silverado?
Bank 2 refers to the side of the engine opposite Bank 1 (usually the side without cylinder 1), and Sensor 2 is the downstream oxygen sensor located after the catalytic converter.
How can I fix the P013C code on a 2015 Chevrolet Silverado?
Common fixes include replacing the Bank 2, Sensor 2 oxygen sensor, repairing wiring or connectors, fixing exhaust leaks, or addressing any contamination issues.
How much does it cost to repair a P013C code on a 2015 Chevrolet Silverado?
The cost of repair varies but typically ranges from $150 to $300 for a replacement oxygen sensor, plus labor if performed by a mechanic.
Can a dirty air filter cause the P013C code on a 2015 Chevrolet Silverado?
A dirty air filter is unlikely to directly cause the P013C code but can affect overall engine performance, which might indirectly influence oxygen sensor readings.
How can I prevent the P013C code from recurring on my 2015 Chevrolet Silverado?
Regular maintenance, including inspecting and cleaning oxygen sensors, repairing exhaust leaks promptly, and using high-quality fuel, can help prevent this code from recurring.
