P013E 2017 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 2017 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 2017 GMC Sierra Code

1. What does the OBDII code P013E mean on a 2017 GMC Sierra?

P013E indicates that the oxygen sensor (HO2S) on Bank 1 Sensor 2 is taking too long to switch from a rich to a lean condition, suggesting a delayed response.

2. What are the common symptoms of P013E in a 2017 GMC Sierra?

Symptoms may include an illuminated check engine light, reduced fuel efficiency, rough idling, or slight hesitation during acceleration.

3. What causes the P013E code in a 2017 GMC Sierra?

Common causes include a faulty downstream oxygen sensor, exhaust leaks, damaged wiring or connectors, or an issue with the engine control module (ECM).

4. Is the P013E code serious on a 2017 GMC Sierra?

While it may not cause immediate drivability issues, ignoring it can lead to reduced fuel efficiency and potential damage to the catalytic converter over time.

5. How do you diagnose the P013E code in a 2017 GMC Sierra?

Diagnosis involves scanning for additional codes, inspecting the oxygen sensor and its wiring, checking for exhaust leaks, and monitoring live data from the oxygen sensor.

6. Can a dirty air filter cause the P013E code on a 2017 GMC Sierra?

While unlikely, a dirty air filter can contribute to improper air-fuel mixture, which may indirectly affect oxygen sensor readings.

7. How do you fix the P013E code on a 2017 GMC Sierra?

Possible fixes include replacing the downstream oxygen sensor, repairing exhaust leaks, fixing damaged wiring, or updating/reprogramming the ECM.

8. How much does it cost to repair the P013E code on a 2017 GMC Sierra?

Replacing a downstream oxygen sensor typically costs between $150 and $300, but costs may vary depending on labor rates and diagnostic needs.

9. Can a P013E code be caused by bad fuel quality in a 2017 GMC Sierra?

Poor fuel quality is unlikely to directly cause P013E, but it can lead to incomplete combustion, which may affect sensor readings.

10. Can I drive my 2017 GMC Sierra with a P013E code?

While the truck may still be drivable, itâ€™s best to address the issue promptly to avoid potential damage to the catalytic converter and ensure optimal performance.
