P013C 2015 GMC Sierra 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 GMC Sierra 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 GMC Sierra?
- 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 GMC Sierra?
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 GMC Sierra Code
What does the OBDII code P013C mean for a 2015 GMC Sierra?
P013C indicates that the downstream oxygen sensor (Bank 2, Sensor 2) is responding too slowly when transitioning from a rich to lean condition.
What are the common symptoms of code P013C in a 2015 GMC Sierra?
Symptoms may include a check engine light, reduced fuel efficiency, and potential difficulty passing emissions tests.
What causes the P013C code to appear in a 2015 GMC Sierra?
Common causes include a faulty oxygen sensor, exhaust leaks, wiring issues, or contamination of the sensor due to oil or coolant.
Can a bad oxygen sensor trigger the P013C code?
Yes, a failing downstream oxygen sensor (Bank 2, Sensor 2) is often the primary cause of this code.
How do I diagnose the P013C code in a 2015 GMC Sierra?
Start by inspecting the wiring and connections to the sensor, then test the oxygen sensor’s response time using a scan tool or multimeter.
Can driving with the P013C code damage my 2015 GMC Sierra?
Driving with this code for an extended period can affect fuel efficiency and emissions but is unlikely to cause immediate damage to the vehicle.
How should I fix the P013C code in a 2015 GMC Sierra?
Repair steps may include replacing the faulty oxygen sensor, fixing exhaust leaks, or addressing wiring issues.
How much does it cost to repair the P013C code on a 2015 GMC Sierra?
Oxygen sensor replacement typically costs between $150 and $300, depending on labor and parts pricing.
Can an exhaust leak cause the P013C code in a 2015 GMC Sierra?
Yes, an exhaust leak near Bank 2, Sensor 2 can disrupt sensor readings and trigger this code.
What tools are needed to fix the P013C code in a 2015 GMC Sierra?
Common tools include a scan tool, multimeter, oxygen sensor socket, and basic hand tools for removing and replacing the sensor.
