Code P113D 2015 GMC Sierra Description
The P113D diagnostic trouble code (DTC) for a 2015 GMC Sierra specifically refers to the Exhaust Gas Temperature Sensor 3 Not Plausible. This code indicates that the data being received from the exhaust gas temperature sensor 3 is not within the expected range or is not consistent with other sensor readings. The exhaust gas temperature sensor is a crucial component of the vehicle's emissions system, as it helps monitor and regulate the temperature of the exhaust gases leaving the engine.
Common Causes of P113D 2015 GMC Sierra
- Faulty Sensor: The most common cause of a P113D code is a faulty exhaust gas temperature sensor 3.
- Wiring Issues: Problems with the wiring or connectors associated with the sensor can also trigger this code.
- Exhaust System Leaks: Leaks in the exhaust system can lead to incorrect sensor readings and trigger the code.
- ECM Malfunction: A malfunctioning engine control module may not be able to interpret the sensor data correctly, leading to the code.
Symptoms of P113D 2015 GMC Sierra
- Check Engine Light: The most common symptom associated with a P113D code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A faulty exhaust gas temperature sensor can result in decreased fuel efficiency, as the ECM may not be able to adjust the fuel mixture accurately.
- Rough Idle: The engine may experience rough idling or hesitation when the sensor is not providing accurate data.
- Emission Issues: The vehicle may fail emissions tests or produce higher emissions than usual due to the inaccurate sensor readings.
How to Fix P113D 2015 GMC Sierra
- Diagnose the Issue: Use a diagnostic scanner to confirm the P113D code and pinpoint the exact cause of the problem.
- Inspect Sensor and Wiring: Check the exhaust gas temperature sensor 3 and its wiring for any visible damage or issues.
- Replace Sensor: If the sensor is faulty, replace it with a new, OEM-quality sensor to ensure accurate readings.
- Repair Wiring: If there are any wiring issues, repair or replace the damaged wiring to ensure proper connection.
- Clear Codes: After completing the repair, clear the DTCs from the ECM and test drive the vehicle to ensure the issue has been resolved.

Frequently Asked Questions about P113D 2015 GMC Sierra Code
1. What does the OBDII code P113D mean on a 2015 GMC Sierra?
The code P113D indicates that the Exhaust Gas Temperature (EGT) Sensor 3 is reporting a value that is not plausible based on the engine's operating conditions.
2. What are the common symptoms of the P113D code?
Symptoms can include a check engine light, poor fuel efficiency, reduced engine performance, or issues with the diesel particulate filter (DPF) regeneration process.
3. What causes the P113D code to appear?
Common causes include a faulty EGT sensor, damaged wiring or connectors, soot buildup on the sensor, or issues with the engine control module (ECM) software.
4. Can I drive with the P113D code on my 2015 GMC Sierra?
Driving with this code is not recommended as it can affect engine performance and may prevent the DPF from regenerating, potentially leading to further damage.
5. How do I fix the P113D code?
Repairs may involve cleaning or replacing the EGT sensor, repairing damaged wiring, or updating the ECM software if necessary.
6. Where is Exhaust Gas Temperature Sensor 3 located on a 2015 GMC Sierra?
EGT Sensor 3 is typically located in the exhaust system downstream of the turbocharger, often near the diesel particulate filter.
7. How can I test the EGT Sensor 3 to confirm it’s faulty?
Use a multimeter to check the sensor’s resistance and compare it to the manufacturer’s specifications. Additionally, inspect the sensor for physical damage or soot buildup.
8. Can a bad EGT sensor cause damage to my engine?
Yes, a malfunctioning EGT sensor can lead to incorrect exhaust temperature readings, which may prevent proper DPF regeneration and cause engine or exhaust system damage over time.
9. Does the P113D code always mean the EGT sensor is bad?
No, the issue could also be caused by wiring problems, connector issues, or ECM software errors, so a thorough diagnosis is necessary.
10. How much does it cost to fix the P113D code on a 2015 GMC Sierra?
Repair costs can vary but typically range from $100 to $300 for sensor replacement, depending on labor rates and parts pricing. Wiring repairs or ECM updates may add to the cost.
