P013E GMC Code - HO2S Delay Response Rich to Lean Bank 1 Sensor 2
Quick Answer
The P013E diagnostic trouble code (DTC) for GMC vehicles refers to a "HO2S Delay Response Rich to Lean Bank 1 Sensor 2" issue. Common causes include Faulty downstream oxygen sensor, Wiring or connector issues in the oxygen sensor circuit, Exhaust leaks near the oxygen sensor. 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 GMC Description
The P013E diagnostic trouble code (DTC) for GMC vehicles refers to a "HO2S Delay Response Rich to Lean Bank 1 Sensor 2" issue. This code indicates that there is a delay in the response of the downstream oxygen sensor (sensor 2) located in bank 1 of the exhaust system, transitioning from a rich (too much fuel) to a lean (too little fuel) air-fuel mixture. The downstream oxygen sensor is responsible for monitoring the efficiency of the catalytic converter and providing feedback to the engine control module (ECM) to adjust the fuel mixture accordingly.
Common Causes of P013E GMC
- Faulty downstream oxygen sensor
- Wiring or connector issues in the oxygen sensor circuit
- Exhaust leaks near the oxygen sensor
- Engine running too rich or too lean
- ECM software or hardware issues
Symptoms of P013E GMC
- Decreased fuel efficiency
- Rough idling or stalling
- Check Engine Light illuminated
- Poor acceleration or hesitation
- Increased emissions output
How to Fix P013E GMC
- Use an OBD-II scanner to confirm the P013E code and identify the specific sensor causing the issue.
- Inspect the downstream oxygen sensor and its wiring for any visible damage or corrosion.
- Replace the downstream oxygen sensor if it is faulty, ensuring to use an OEM or high-quality replacement part.
- Clear the DTC and perform a test drive to monitor the sensor's response and verify that the issue has been resolved.
- If the problem persists, further diagnosis may be needed to check for any underlying wiring or ECM issues.
Cost to Fix P013E GMC
The typical repair costs for addressing a P013E code can range from $150 to $400, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's recommended to inquire with local auto repair shops for a more accurate estimate.
