Code P013C 2017 GMC Sierra Description
The P013C diagnostic trouble code (DTC) for a 2017 GMC Sierra refers to a "HO2S Slow Response Rich to Lean Bank 2 Sensor 2" issue. This code indicates that there is a problem with the oxygen sensor (O2 sensor) located in bank 2, sensor 2 of the vehicle's exhaust system. The O2 sensor is responsible for measuring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P013C 2017 GMC Sierra
- Faulty O2 sensor in bank 2, sensor 2
- Wiring or connector issues in the O2 sensor circuit
- Exhaust leaks near the O2 sensor
- Vacuum leaks in the intake system
- Fuel system issues, such as a clogged fuel injector
Symptoms of P013C 2017 GMC Sierra
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Check Engine Light illuminated
- Increased emissions
How to Fix P013C 2017 GMC Sierra
- Diagnose the O2 sensor in bank 2, sensor 2 using a scan tool to confirm the slow response issue.
- Inspect the wiring and connectors in the O2 sensor circuit for any damage or corrosion.
- Check for exhaust leaks near the O2 sensor and repair as necessary.
- Perform a smoke test to identify and repair any vacuum leaks in the intake system.
- Test the fuel system components, such as fuel injectors, for proper operation and replace any faulty parts.
Cost to Fix P013C 2017 GMC Sierra
The typical repair costs for addressing a P013C code on a 2017 GMC Sierra can range from $200 to $500, 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. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships. Independent shops often offer lower labor rates. It is advisable to obtain quotes from local repair shops for a more accurate estimate of the total repair costs.

Frequently Asked Questions about P013C 2017 GMC Sierra Code
1. What does the OBDII code P013C mean on a 2017 GMC Sierra?
P013C indicates "HO2S Slow Response Rich to Lean Bank 2 Sensor 2," meaning the downstream oxygen sensor on Bank 2 is not switching between rich and lean as expected.
2. What are the symptoms of code P013C on a 2017 GMC Sierra?
Common symptoms include a lit check engine light, decreased fuel efficiency, potential emissions test failure, and possibly a slight reduction in engine performance.
3. What causes the P013C code on a 2017 GMC Sierra?
The primary causes include a faulty oxygen sensor (Bank 2, Sensor 2), damaged wiring or connections, exhaust leaks, or contamination of the sensor due to oil or coolant leaks.
4. Can I still drive my 2017 GMC Sierra with a P013C code?
Yes, but it is not recommended to drive for extended periods as it may lead to increased emissions, reduced fuel efficiency, and potential damage to other components like the catalytic converter.
5. How do I fix the P013C code on my 2017 GMC Sierra?
Repairs may include replacing the Bank 2 Sensor 2 oxygen sensor, repairing damaged wiring or connectors, addressing any exhaust leaks, or resolving issues like oil or coolant contamination.
6. How do I locate Bank 2 Sensor 2 on a 2017 GMC Sierra?
Bank 2 is the side of the engine opposite the number one cylinder (passenger side on a V8 engine), and Sensor 2 refers to the downstream oxygen sensor located after the catalytic converter on that side.
7. What tools are needed to diagnose and fix a P013C code?
You’ll need an OBDII scanner, a multimeter for testing wiring, and possibly a socket wrench with an O2 sensor socket for sensor replacement.
8. Can a bad catalytic converter cause the P013C code?
While not a direct cause, a failing catalytic converter might lead to irregular exhaust flow, potentially affecting oxygen sensor readings and triggering this code.
9. How much does it cost to repair the P013C code on a 2017 GMC Sierra?
The cost can range from $150 to $400, depending on whether only the oxygen sensor needs replacement or if additional repairs like fixing an exhaust leak are required.
10. Can a dirty air filter trigger the P013C code on a 2017 GMC Sierra?
While unlikely, a severely clogged air filter can lead to improper air-fuel mixtures, potentially affecting oxygen sensor behavior and contributing to sensor-related codes.
