P013E 2015 Chevrolet Silverado Code - HO2S Delay Response Rich to Lean 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 P013E 2015 Chevrolet Silverado 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 decreased below 450 mV within a calibrated value of accumulated airflow.
What are the Possible Causes of the DTC P013E 2015 Chevrolet Silverado?
- 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 P013E 2015 Chevrolet Silverado?
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.

P013E indicates that the downstream oxygen sensor (Bank 1 Sensor 2) is responding too slowly when transitioning from a rich to lean condition.
2. What are the common symptoms of code P013E?
Symptoms may include an illuminated check engine light, reduced fuel efficiency, and occasional rough idling or hesitation during acceleration.
3. What causes code P013E on a Chevrolet Silverado?
Common causes include a faulty downstream oxygen sensor, exhaust leaks, wiring issues, or contamination of the sensor from oil or coolant.
4. How can I diagnose code P013E on my 2015 Silverado?
Start by inspecting the oxygen sensor and its wiring for damage. Use a scan tool to monitor live O2 sensor data and check for abnormal readings or slow response times.
5. Can a dirty or contaminated oxygen sensor trigger code P013E?
Yes, contamination from oil, coolant, or carbon buildup can affect the sensor's ability to function properly and lead to this code.
6. Is it safe to drive with code P013E on my Silverado?
While it may be safe to drive short distances, prolonged driving with this code can affect fuel efficiency and engine performance, so repairs should be done promptly.
7. How do I fix code P013E on a 2015 Chevrolet Silverado?
Repairs may include replacing the Bank 1 Sensor 2 oxygen sensor, fixing exhaust leaks, or repairing damaged wiring and connectors.
8. How much does it cost to fix code P013E?
The cost varies depending on the repair needed. Replacing the oxygen sensor typically costs $150–$300, while wiring or exhaust repairs may increase the cost.
9. Can a P013E code be caused by an exhaust leak?
Yes, an exhaust leak near the sensor can disrupt readings and cause this code.
10. Do I need to replace all oxygen sensors to fix code P013E?
No, only Bank 1 Sensor 2 needs attention unless diagnostics reveal issues with other sensors or components.
