P013A 2016 Chevrolet Silverado Code - HO2S Slow 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 P013A 2016 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 accumulated mass airflow monitored during rich-to-lean transitions between 450 - 150 mV is greater than calibrated value.
What are the Possible Causes of the DTC P013A 2016 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 P013A 2016 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.

Frequently Asked Questions about P013A 2016 Chevrolet Silverado Code
What does the OBDII code P013A mean for a 2016 Chevrolet Silverado?
P013A indicates that the oxygen sensor (HO2S) on Bank 1 Sensor 2 is responding too slowly when switching from a rich to a lean condition.
What are the symptoms of a P013A code in a 2016 Chevy Silverado?
Common symptoms include an illuminated check engine light, potential decrease in fuel efficiency, and possibly rough idling or engine hesitation.
What causes the P013A code to appear on a 2016 Chevrolet Silverado?
Possible causes include a faulty downstream oxygen sensor (Bank 1 Sensor 2), exhaust leaks, wiring or connector issues, or contamination of the oxygen sensor.
Can I drive my 2016 Chevrolet Silverado with a P013A code?
While the vehicle may still be drivable, ignoring the code can lead to reduced fuel efficiency and potential damage to other components, such as the catalytic converter.
How do I fix the P013A code on a 2016 Chevrolet Silverado?
Common fixes include replacing the oxygen sensor, repairing exhaust leaks, checking for and repairing damaged wiring, and inspecting the sensor for contamination.
Where is Bank 1 Sensor 2 located on a 2016 Chevrolet Silverado?
Bank 1 Sensor 2 is the downstream oxygen sensor located after the catalytic converter on the side of the engine with cylinder 1.
How do I know if the oxygen sensor is faulty and causing the P013A code?
You can test the oxygen sensor using a multimeter or scan tool to check its response time and voltage readings, or have it inspected by a professional mechanic.
Can an exhaust leak cause the P013A code on my 2016 Silverado?
Yes, an exhaust leak can allow extra oxygen into the system, leading to inaccurate readings from the oxygen sensor and triggering the P013A code.
How much does it cost to fix a P013A code on a 2016 Chevrolet Silverado?
Repair costs can range from $150 to $400 or more, depending on whether the oxygen sensor needs replacement or if additional repairs, like fixing an exhaust leak, are required.
Does the P013A code affect emissions on a 2016 Chevy Silverado?
Yes, a slow-responding oxygen sensor can impact the air-fuel mixture and cause higher emissions, which may lead to a failed emissions test.
