P113C 2016 GMC Sierra Code - Exhaust Gas Temperature Sensor 2 Not Plausible
Quick Answer
The P113C diagnostic trouble code (DTC) for a 2016 GMC Sierra specifically indicates a problem with the Exhaust Gas Temperature Sensor 2 not being plausible. Common causes include Faulty Exhaust Gas Temperature Sensor 2: The sensor itself may be malfunctioning or damaged, leading to inaccurate data being sent to the ECM, Wiring or Connector Issues: Corrosion, damage, or loose connections in the wiring harness or connectors associated with the sensor can disrupt the signal, ECM Malfunction: In some cases, the issue may lie with the engine control module not processing the sensor data correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P113C 2016 GMC Sierra Description
The P113C diagnostic trouble code (DTC) for a 2016 GMC Sierra specifically indicates a problem with the Exhaust Gas Temperature Sensor 2 not being plausible. This sensor is responsible for monitoring the exhaust gas temperature in the vehicle's exhaust system. The information gathered by this sensor is crucial for the engine control module (ECM) to adjust fuel delivery and optimize engine performance. When the ECM detects that the data from Exhaust Gas Temperature Sensor 2 is not plausible or does not align with the expected values, it triggers the P113C code.
Common Causes of P113C 2016 GMC Sierra
- Faulty Exhaust Gas Temperature Sensor 2: The sensor itself may be malfunctioning or damaged, leading to inaccurate data being sent to the ECM.
- Wiring or Connector Issues: Corrosion, damage, or loose connections in the wiring harness or connectors associated with the sensor can disrupt the signal.
- ECM Malfunction: In some cases, the issue may lie with the engine control module not processing the sensor data correctly.
- Exhaust System Leaks: Any leaks in the exhaust system can affect the readings of the sensor, triggering the P113C code.
- Exhaust Gas Temperature Sensor 2 Placement: If the sensor is improperly placed or installed, it may not be able to accurately measure the exhaust gas temperature.
Symptoms of P113C 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P113C code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning exhaust gas temperature sensor can lead to decreased fuel efficiency as the ECM may not be able to adjust fuel delivery accurately.
- Engine Performance Issues: The vehicle may experience rough idling, hesitation, or lack of power due to incorrect data from the sensor.
- Increased Emissions: If the sensor is not functioning correctly, it can result in increased emissions from the vehicle.
How to Fix P113C 2016 GMC Sierra
- Diagnostic Scan: Begin by using a diagnostic scanner to retrieve the trouble codes and confirm that P113C is related to the Exhaust Gas Temperature Sensor 2.
- Inspection: Inspect the sensor, wiring, and connectors for any visible damage, corrosion, or loose connections. Replace or repair any faulty components.
- Sensor Replacement: If the sensor is determined to be faulty, replace it with a new, OEM-quality part. Ensure proper installation and calibration.
- Clear Codes: After the repair is completed, clear the trouble codes from the ECM's memory using the diagnostic scanner.
- Test Drive: Take the vehicle for a test drive to ensure that the Check Engine Light does not reappear and that the vehicle's performance and fuel efficiency have been restored.
Cost to Fix P113C 2016 GMC Sierra
The typical repair costs for addressing the P113C code related to the Exhaust Gas Temperature Sensor 2 not being plausible can vary depending on the specific cause of the issue and the labor rates in your area. In general, the cost of replacing the sensor itself can range from $100 to $300, with additional costs for labor and diagnostic time. Overall, you can expect the total repair cost to fall between $200 and $500, but it's advisable to consult with a professional mechanic or auto repair shop for a more accurate estimate based on your vehicle's make and model. Keep in mind that labor rates can vary significantly, so it's essential to inquire about the specific rates at your chosen repair facility.

Frequently Asked Questions about P113C 2016 GMC Sierra Code
1. What does the OBDII code P113C mean on a 2016 GMC Sierra?
P113C indicates that the Exhaust Gas Temperature (EGT) Sensor 2 is reporting values that are not plausible or outside the expected range, suggesting a potential sensor fault or related issue.
2. What are the symptoms of the P113C code in a 2016 GMC Sierra?
Common symptoms include an illuminated check engine light, reduced fuel efficiency, potential power loss, and, in some cases, the vehicle entering "limp mode."
3. What causes the P113C code to appear on a 2016 GMC Sierra?
Possible causes include a faulty Exhaust Gas Temperature Sensor 2, damaged wiring or connectors, soot buildup on the sensor, or issues with the vehicle's exhaust system or ECU.
4. Can I drive my 2016 GMC Sierra with the P113C code?
While the vehicle may still be drivable, it's not recommended since ignoring the issue could lead to reduced performance, increased emissions, and potential damage to the exhaust system or other components.
5. How is the P113C code diagnosed?
A mechanic will typically use a scan tool to confirm the code, inspect the EGT sensor and wiring for damage, and measure the sensor's resistance or voltage output to verify its operation.
6. How do you fix the P113C code on a 2016 GMC Sierra?
Repairs may include replacing the faulty EGT sensor, cleaning or repairing damaged wiring or connectors, clearing soot from the sensor, or reprogramming the ECU if necessary.
7. How much does it cost to fix the P113C code on a 2016 GMC Sierra?
Repair costs vary but typically range from $150 to $300 for sensor replacement, depending on labor rates and parts pricing.
8. Where is Exhaust Gas Temperature Sensor 2 located on a 2016 GMC Sierra?
Sensor 2 is usually located downstream in the exhaust system, often near the diesel particulate filter (DPF) or catalytic converter, depending on the exact configuration of the vehicle.
9. Can a dirty or clogged exhaust system cause the P113C code?
Yes, soot buildup or clogging in the exhaust system can affect the EGT sensor's readings and trigger this code.
10. Do I need to clear the P113C code manually after repairs?
After repairs, the code may need to be cleared using an OBDII scan tool, although the ECU may clear it automatically after several successful drive cycles.
