P013D 2018 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 2018 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 2018 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 2018 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 2018 GMC Sierra Code
What does the OBDII code P013D mean on a 2018 GMC Sierra?
P013D indicates that the oxygen sensor (HO2S) in Bank 2 Sensor 2 has a slow response time when switching from a lean to rich condition, suggesting a potential issue with the sensor or exhaust system.
What are the symptoms of a P013D code in a 2018 GMC Sierra?
Common symptoms include an illuminated check engine light, decreased fuel efficiency, rough idling, and potential difficulty passing emissions tests.
What causes the P013D code in a 2018 GMC Sierra?
Possible causes include a faulty oxygen sensor, exhaust leaks, wiring issues, a malfunctioning catalytic converter, or engine performance problems affecting air-fuel ratios.
How do I diagnose a P013D code on my 2018 GMC Sierra?
Begin by using an OBDII scanner to confirm the code, inspect the wiring and connectors for damage, check for exhaust leaks, and test the oxygen sensor’s response time with a multimeter or diagnostic tool.
Can I drive my 2018 GMC Sierra with a P013D code?
While the vehicle may still be drivable, it’s not recommended to ignore the issue as it may lead to poor fuel economy, increased emissions, or damage to other components like the catalytic converter.
How do I fix the P013D code on a 2018 GMC Sierra?
Potential fixes include replacing a faulty oxygen sensor, repairing any exhaust leaks, addressing wiring or connector issues, and ensuring proper engine performance and air-fuel ratio.
How much does it cost to repair a P013D code on a 2018 GMC Sierra?
Repair costs vary depending on the issue but typically range from $150 to $300 for oxygen sensor replacement. Additional repairs like fixing exhaust leaks may raise the cost.
Can a P013D code be caused by bad fuel?
While rare, poor-quality fuel can contribute to improper combustion and air-fuel imbalances, indirectly affecting oxygen sensor performance and triggering the code.
Do I need to replace both oxygen sensors if I have a P013D code?
Not necessarily. The code specifically refers to Bank 2 Sensor 2. Diagnose and replace only the faulty sensor unless there are issues with others.
Will clearing the P013D code fix the problem?
Clearing the code may turn off the check engine light temporarily, but it won’t resolve the underlying issue. Proper diagnosis and repair are required to fix the problem.
