P113F 2017 Chevrolet Silverado Code - Exhaust Gas Temperature Sensor 5 Not Plausible

Quick Answer

The P113F code indicates that the Engine Control Module (ECM) has detected an inconsistency or implausibility in the readings from Exhaust Gas Temperature (EGT) Sensor 5. Common causes include Faulty EGT Sensor 5: The sensor itself may be malfunctioning or damaged, leading to inaccurate readings, Wiring Issues: Damaged or corroded wiring and connectors associated with the EGT sensor can disrupt the signal sent to the ECM, Exhaust Leaks: Leaks in the exhaust system can cause incorrect temperature readings, triggering the code. 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 P113F 2017 Chevrolet Silverado Description

The P113F code indicates that the Engine Control Module (ECM) has detected an inconsistency or implausibility in the readings from Exhaust Gas Temperature (EGT) Sensor 5. This sensor is crucial for monitoring the temperature of exhaust gases, which is vital for optimizing combustion efficiency, emissions control, and overall engine performance. The EGT sensors play a significant role in the operation of the vehicle's emissions system, particularly in diesel engines where they help manage the Diesel Particulate Filter (DPF) and the Selective Catalytic Reduction (SCR) systems.

Common Causes of P113F 2017 Chevrolet Silverado

  1. Faulty EGT Sensor 5: The sensor itself may be malfunctioning or damaged, leading to inaccurate readings.
  2. Wiring Issues: Damaged or corroded wiring and connectors associated with the EGT sensor can disrupt the signal sent to the ECM.
  3. Exhaust Leaks: Leaks in the exhaust system can cause incorrect temperature readings, triggering the code.
  4. ECM Malfunction: A failure or software issue within the ECM may misinterpret the data from the EGT sensor.
  5. Contaminated Sensor: Deposits or soot buildup on the sensor can affect its ability to accurately measure exhaust gas temperatures.

Symptoms of P113F 2017 Chevrolet Silverado

  1. Check Engine Light: The most immediate symptom is the illumination of the check engine light on the dashboard.
  2. Poor Fuel Economy: Drivers may notice a decrease in fuel efficiency due to improper fuel-air mixture adjustments.
  3. Increased Emissions: The vehicle may produce higher emissions, potentially leading to failing emissions tests.
  4. Rough Idle or Stalling: The engine may experience rough idling or stalling due to incorrect readings affecting fuel delivery.
  5. Loss of Power: Drivers might feel a noticeable loss of power during acceleration, especially under load.

How to Fix P113F 2017 Chevrolet Silverado

  1. Diagnostic Scan: Begin with a thorough diagnostic scan to confirm the P113F code and check for any related codes.
  2. Visual Inspection: Inspect the wiring and connectors associated with EGT Sensor 5 for signs of damage, corrosion, or loose connections.
  3. Sensor Replacement: If the sensor is found to be faulty, replace EGT Sensor 5 with a new, OEM-quality part.
  4. Exhaust System Check: Inspect the exhaust system for leaks or blockages that could affect sensor readings, and repair as necessary.
  5. ECM Reprogramming: If the ECM is suspected to be at fault, it may require reprogramming or replacement to ensure proper functionality.

Cost to Fix P113F 2017 Chevrolet Silverado

Repair costs for addressing the P113F code can vary widely based on several factors, including the specific diagnosis time, parts needed, and labor rates in your area. Typically, the cost for parts (such as a new EGT sensor) can range from $100 to $300, while labor costs can vary from $80 to $150 per hour. The total repair cost may range from $200 to $600, depending on the complexity of the issue and the specific repairs required. It's important to note that labor rates can be higher at dealerships or in metropolitan areas, while independent shops may offer more competitive pricing. For the most accurate estimate, it's advisable to consult local repair shops for quotes tailored to your vehicle's make and model.
