P013D 2015 GMC Sierra Code - HO2S Slow Response Lean to Rich 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 P013D 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 lean-to-rich transitions between 350 - 650 mV is greater than calibrated value.
What are the Possible Causes of the DTC P013D 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 P013D 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 P013D 2015 GMC Sierra Code
1. What does the OBDII code P013D mean on a 2015 GMC Sierra?
P013D indicates that the oxygen sensor (HO2S) on Bank 2 Sensor 2 is detecting a slow response when transitioning from a lean to a rich air-fuel mixture.
2. What are the symptoms of code P013D on a GMC Sierra?
Common symptoms include an illuminated check engine light, decreased fuel efficiency, rough idling, or no noticeable symptoms at all in some cases.
3. What causes the P013D code to appear?
Possible causes include a faulty Bank 2 Sensor 2 oxygen sensor, exhaust leaks, wiring or connector issues, or a malfunctioning catalytic converter.
4. How do I fix the P013D code on my 2015 GMC Sierra?
Repairs may involve replacing the faulty oxygen sensor, repairing damaged wiring or connectors, fixing exhaust leaks, or replacing the catalytic converter if necessary.
5. Can I drive my GMC Sierra with the P013D code?
While the vehicle may still be drivable, prolonged operation with this code could lead to reduced fuel efficiency and potential damage to the catalytic converter.
6. How do I diagnose the P013D code on a 2015 GMC Sierra?
Start by using a scan tool to confirm the code, inspect the Bank 2 Sensor 2 oxygen sensor and its wiring, check for exhaust leaks, and test the catalytic converter's efficiency.
7. Is the P013D code specific to Bank 2 Sensor 2?
Yes, P013D specifically refers to the downstream oxygen sensor on Bank 2, which monitors the catalytic converter's performance.
8. How much does it cost to fix the P013D code?
The cost varies but typically ranges from $100-$300 for an oxygen sensor replacement, depending on labor rates and parts pricing. Additional repairs, like fixing exhaust leaks, may increase the cost.
9. Can a dirty air filter cause the P013D code?
A dirty air filter is unlikely to directly cause P013D, but other air-fuel mixture issues could contribute to the sensor's slow response.
10. Will clearing the code fix the P013D issue?
Clearing the code will turn off the check engine light temporarily, but if the underlying issue isn’t resolved, the code will likely return.
