P113B 2014 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 1 Not Plausible
Quick Answer
The P113B diagnostic trouble code (DTC) indicates that the Engine Control Module (ECM) has detected an inconsistency in the readings from the Exhaust Gas Temperature (EGT) Sensor 1. Common causes include Faulty EGT Sensor: The sensor itself may be defective or malfunctioning, leading to incorrect readings, Wiring Issues: Damaged, frayed, or corroded wiring or connectors associated with the EGT sensor can cause signal loss or interference, Exhaust Leaks: Leaks in the exhaust system can lead to incorrect temperature readings at the sensor. 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 P113B 2014 Chevrolet Silverado Description
The P113B diagnostic trouble code (DTC) indicates that the Engine Control Module (ECM) has detected an inconsistency in the readings from the Exhaust Gas Temperature (EGT) Sensor 1. This sensor is critical in monitoring the temperature of the exhaust gases as they exit the engine, which helps the ECM optimize fuel injection and ignition timing for improved performance and emissions control. When the ECM receives data that is not plausible—meaning the temperature readings fall outside expected parameters—it triggers this code.
Common Causes of P113B 2014 Chevrolet Silverado
- Faulty EGT Sensor: The sensor itself may be defective or malfunctioning, leading to incorrect readings.
- Wiring Issues: Damaged, frayed, or corroded wiring or connectors associated with the EGT sensor can cause signal loss or interference.
- Exhaust Leaks: Leaks in the exhaust system can lead to incorrect temperature readings at the sensor.
- Contaminated Sensor: Build-up of soot or other contaminants on the sensor can affect its ability to accurately measure exhaust gas temperature.
- ECM Malfunction: In rare cases, the issue may stem from a malfunction within the ECM itself, leading to incorrect interpretation of sensor data.
Symptoms of P113B 2014 Chevrolet Silverado
- Check Engine Light: The most immediate symptom is the illumination of the check engine light on the dashboard.
- Poor Fuel Economy: Drivers may notice a decrease in fuel efficiency due to improper air-fuel mixture adjustments.
- Reduced Engine Performance: The vehicle may experience sluggish acceleration or difficulty maintaining speed.
- Increased Emissions: The vehicle may fail emissions tests due to improper combustion and exhaust management.
- Engine Overheating: In severe cases, the engine may run hotter than normal due to inefficient fuel combustion.
How to Fix P113B 2014 Chevrolet Silverado
- Diagnostic Scan: Begin with a thorough diagnostic scan to confirm the P113B code and check for any related codes that may provide additional context.
- Visual Inspection: Conduct a visual inspection of the EGT sensor, wiring, and connectors for signs of damage, corrosion, or disconnection.
- Sensor Replacement: If the EGT sensor is found to be faulty, replace it with a new, OEM-quality sensor to ensure accurate readings.
- Repair Wiring Issues: If wiring or connectors are damaged, repair or replace them as necessary to restore proper electrical connections.
- Clear Codes and Test Drive: After repairs, clear the DTCs from the ECM and conduct a test drive to ensure the issue is resolved and the check engine light does not reappear.
Cost to Fix P113B 2014 Chevrolet Silverado
The cost to repair a P113B code can vary significantly based on the specific diagnosis and repairs needed. On average, the cost for parts and labor can range from $150 to $600. This estimate includes the price of a new EGT sensor, which typically costs between $50 and $200, and labor costs, which can range from $80 to $150 per hour depending on the shop's location and reputation. In metropolitan areas or at dealerships, labor rates may be higher, while independent shops often offer more competitive pricing. It’s advisable to check local rates and get multiple quotes for a more precise estimate tailored to your specific situation.
