P113C 2015 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 2 Not Plausible
Quick Answer
The P113C diagnostic trouble code (DTC) specifically pertains to the Exhaust Gas Temperature Sensor 2 (EGT) not providing plausible data to the engine control module (ECM) in a 2015 Chevrolet Silverado. Common causes include Faulty EGT Sensor: The most common cause of this code is a malfunctioning or failed EGT sensor, Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can also trigger this code, ECM Software Issue: In some cases, a software glitch or ECM programming error can cause the EGT sensor to provide implausible data. 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 2015 Chevrolet Silverado Description
The P113C diagnostic trouble code (DTC) specifically pertains to the Exhaust Gas Temperature Sensor 2 (EGT) not providing plausible data to the engine control module (ECM) in a 2015 Chevrolet Silverado. The EGT sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. This information is crucial for the ECM to optimize fuel injection and emission control strategies. When the EGT sensor 2 does not provide plausible data, it can lead to incorrect fueling and potentially affect the vehicle's performance and emissions.
Common Causes of P113C 2015 Chevrolet Silverado
- Faulty EGT Sensor: The most common cause of this code is a malfunctioning or failed EGT sensor.
- Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can also trigger this code.
- ECM Software Issue: In some cases, a software glitch or ECM programming error can cause the EGT sensor to provide implausible data.
- Exhaust System Leak: An exhaust system leak near the EGT sensor can lead to inaccurate readings and trigger this code.
Symptoms of P113C 2015 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Fuel Efficiency: The vehicle may experience decreased fuel efficiency due to incorrect fueling caused by inaccurate EGT sensor readings.
- Poor Engine Performance: Inaccurate sensor data can lead to suboptimal engine performance, including rough idling or hesitation during acceleration.
- Increased Emissions: A malfunctioning EGT sensor can result in increased emissions, potentially causing the vehicle to fail emissions tests.
How to Fix P113C 2015 Chevrolet Silverado
- Diagnose the EGT Sensor: Use an OBD-II scanner to retrieve the specific code and verify that the EGT sensor 2 is the culprit.
- Inspect Wiring and Connections: Check the wiring harness and connectors for any damage or corrosion. Repair or replace as needed.
- Replace EGT Sensor: If the sensor is found to be faulty, replace it with a new one following manufacturer guidelines.
- Clear Codes and Test Drive: Clear the DTC from the ECM memory, and test drive the vehicle to ensure the issue has been resolved.
- Monitor System: After the repair, monitor the EGT sensor readings to confirm that they are now within the expected range.
Cost to Fix P113C 2015 Chevrolet Silverado
The typical repair costs for addressing a P113C code in a 2015 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, the cost of a new EGT sensor can range from $50 to $150. Labor costs for diagnosis, replacement, and testing can add an additional $100 to $300, depending on the shop rates and location. Overall, the total repair cost for this issue could range from $150 to $450. It is advisable to contact local auto repair shops for a more accurate estimate based on your specific circumstances.

Frequently Asked Questions about P113C 2015 Chevrolet Silverado Code
1. What does the OBDII code P113C mean on a 2015 Chevrolet Silverado?
P113C indicates an issue with Exhaust Gas Temperature (EGT) Sensor 2, where the sensor's readings are not plausible or outside the expected range.
2. What are the symptoms of the P113C code on a 2015 Chevrolet Silverado?
Common symptoms include decreased fuel efficiency, reduced engine performance, the Check Engine Light turning on, and potential issues with the vehicle’s emissions system.
3. What causes the P113C code to appear?
This code is often caused by a faulty EGT sensor, damaged wiring or connectors, excessive soot buildup on the sensor, or an issue with the Engine Control Module (ECM).
4. How can I fix the P113C code on my 2015 Chevrolet Silverado?
Repairs may include replacing the faulty EGT sensor, cleaning soot buildup, repairing damaged wiring or connectors, or reprogramming/updating the ECM if necessary.
5. Can I drive with the P113C code active?
Driving with this code is not recommended as it can lead to increased emissions, reduced fuel efficiency, and potential damage to the exhaust or emissions systems.
6. How is the P113C code diagnosed?
A technician will typically use a scan tool to read live data, inspect the EGT sensor and wiring for damage, and verify the plausibility of the sensor readings.
7. How much does it cost to fix the P113C code?
The repair cost can range from $100 to $300, depending on whether the issue is a faulty sensor, wiring repair, or ECM reprogramming.
8. Where is Exhaust Gas Temperature Sensor 2 located on a 2015 Chevrolet Silverado?
EGT Sensor 2 is usually located in the exhaust system downstream of the turbocharger, often near the Diesel Particulate Filter (DPF).
9. Can a dirty or clogged DPF cause the P113C code?
Yes, a clogged DPF can cause excessive heat or pressure in the exhaust system, leading to implausible readings from the EGT sensor.
10. Will clearing the code fix the P113C issue permanently?
Clearing the code will not fix the issue permanently; the underlying problem must be diagnosed and repaired to prevent the code from returning.
