P013F 2017 GMC Sierra Code - HO2S Delay Response Lean to Rich Bank 1 Sensor 2
Quick Answer
The Heated Oxygen Sensors (HO2S) are used for fuel control and catalyst monitoring. Common causes include Faulty Heated Oxygen Bank 1 Sensor 2, Heated Oxygen Bank 1 Sensor 2 harness is open or shorted, Heated Oxygen Bank 1 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 P013F 2017 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 O2 sensor voltage has not increased above 350 mV within a calibrated value of accumulated airflow.
What are the Possible Causes of the DTC P013F 2017 GMC Sierra?
- Faulty Heated Oxygen Bank 1 Sensor 2
- Heated Oxygen Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Bank 1 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 P013F 2017 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 P013F 2017 GMC Sierra Code
What does the OBDII code P013F mean on a 2017 GMC Sierra?
P013F indicates that the oxygen sensor (HO2S) on Bank 1 Sensor 2 is taking too long to switch from a lean to a rich condition, suggesting a potential issue with the sensor or related components.
What are the symptoms of a P013F code in a 2017 GMC Sierra?
Common symptoms include an illuminated check engine light, decreased fuel efficiency, rough idling, or poor engine performance.
What causes the P013F code to appear on a 2017 GMC Sierra?
The code can be triggered by a faulty oxygen sensor, exhaust leaks, a damaged wiring harness, or issues with the engine control module (ECM).
Is it safe to drive a 2017 GMC Sierra with a P013F code?
While the vehicle may still be drivable, ignoring the issue can lead to reduced fuel efficiency and potentially damage the catalytic converter over time.
How do you diagnose a P013F code on a 2017 GMC Sierra?
A technician will inspect the oxygen sensor, check for exhaust leaks, test the wiring and connectors, and use a scan tool to monitor sensor performance.
Can a dirty or failing oxygen sensor cause the P013F code?
Yes, a dirty or failing oxygen sensor can cause delayed responses and trigger the P013F code.
Can an exhaust leak cause the P013F code on a 2017 GMC Sierra?
Yes, an exhaust leak can disrupt the oxygen sensor's readings and lead to a P013F code.
How do you fix the P013F code on a 2017 GMC Sierra?
Repairs may include replacing the oxygen sensor, fixing exhaust leaks, repairing or replacing damaged wiring, or reprogramming the ECM if necessary.
How much does it cost to repair a P013F code on a 2017 GMC Sierra?
Repair costs vary depending on the issue, but replacing an oxygen sensor typically ranges from $150 to $300, including parts and labor.
Can a bad catalytic converter cause the P013F code?
While rare, a failing catalytic converter can indirectly affect oxygen sensor performance and trigger the P013F code.
