P013E 2016 GMC Sierra 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 2016 GMC Sierra Description

The Heated Oxygen Sensors (HO2S) are used for fuel control and catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content of the exhaust stream. When the engine is started, the Engine Control Module (ECM) operates in an Open Loop mode, ignoring the HO2S signal voltage while calculating the air-to-fuel ratio. While the engine runs, the HO2S heats up and begins to generate a voltage within a range of 0 - 1, 000 mV. Once sufficient HO2S voltage fluctuation is observed by the ECM, Closed Loop is entered. The ECM uses the HO2S voltage to determine the air-to-fuel ratio. An HO2S voltage that increases toward 1, 000 mV indicates a rich fuel mixture. An HO2S voltage that decreases toward 0 mV indicates a lean fuel mixture.
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.

Frequently Asked Questions about P013E 2016 GMC Sierra Code

1. What does the OBDII code P013E mean on a 2016 GMC Sierra?

P013E indicates the oxygen sensor (HO2S) on Bank 1 Sensor 2 has a delayed response when switching from rich to lean conditions.

2. What are the symptoms of a P013E code on a 2016 GMC Sierra?

Common symptoms include poor fuel economy, a potential check engine light, and possibly rough idling or reduced engine performance.

3. What causes the P013E code on a 2016 GMC Sierra?

The code can be triggered by a faulty oxygen sensor, exhaust leaks, wiring or connector issues, or a malfunctioning engine control module (ECM).

4. Which oxygen sensor is Bank 1 Sensor 2 on a 2016 GMC Sierra?

Bank 1 Sensor 2 refers to the downstream oxygen sensor located after the catalytic converter on the side of the engine with cylinder 1.

5. Can an exhaust leak cause the P013E code?

Yes, an exhaust leak near the oxygen sensor can cause inaccurate readings and trigger the P013E code.

6. How do you diagnose the P013E code on a 2016 GMC Sierra?

Diagnosis typically involves using an OBDII scanner to read live data, inspecting the oxygen sensor and its wiring, checking for exhaust leaks, and testing fuel trims.

7. Can a dirty air filter cause the P013E code on a 2016 GMC Sierra?

While unlikely, a severely clogged air filter can impact the air-fuel mixture and indirectly affect oxygen sensor performance.

8. How do you fix the P013E code on a 2016 GMC Sierra?

Repairs may include replacing the downstream oxygen sensor, fixing any exhaust leaks, repairing damaged wiring, or reprogramming the ECM if needed.

9. Can I drive my 2016 GMC Sierra with a P013E code?

Driving with a P013E code is possible but not recommended, as it may lead to decreased fuel efficiency and potential damage to the catalytic converter.

10. How much does it cost to fix the P013E code on a 2016 GMC Sierra?

Repair costs can range from $150 to $400, depending on whether the issue is with the oxygen sensor, wiring, or another related component.
