P245D 2015 Chevrolet Silverado Code - Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage
Quick Answer
The P245D diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado refers to an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit having high voltage. Common causes include Faulty EGR Valve: A malfunctioning EGR valve can disrupt the flow of exhaust gases through the EGR system, triggering the P245D code, Wiring or Connector Issues: Damaged wiring or connectors in the EGR Cooler Bypass Control Circuit can cause electrical malfunctions and high voltage readings, EGR Cooler Malfunction: A faulty EGR cooler can impact the temperature of the recirculated gases, leading to issues with the EGR system. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P245D 2015 Chevrolet Silverado Description
The P245D diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado refers to an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit having high voltage. The EGR system is crucial for reducing emissions and improving fuel efficiency by recirculating a portion of the exhaust gases back into the intake manifold. The EGR Cooler Bypass Control Circuit is responsible for regulating the flow of exhaust gases through the EGR cooler, which helps to lower the temperature of the recirculated gases.
Common Causes of P245D 2015 Chevrolet Silverado
- Faulty EGR Valve: A malfunctioning EGR valve can disrupt the flow of exhaust gases through the EGR system, triggering the P245D code.
- Wiring or Connector Issues: Damaged wiring or connectors in the EGR Cooler Bypass Control Circuit can cause electrical malfunctions and high voltage readings.
- EGR Cooler Malfunction: A faulty EGR cooler can impact the temperature of the recirculated gases, leading to issues with the EGR system.
- ECM Problems: Issues with the engine control module (ECM) that controls the EGR system can result in the circuit operating outside of normal parameters.
- Carbon Buildup: Excessive carbon buildup in the EGR system can restrict the flow of exhaust gases, causing the system to malfunction.
Symptoms of P245D 2015 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P245D code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in power and acceleration due to the EGR system not functioning properly.
- Rough Idling: The engine may idle roughly or inconsistently, leading to a shaky or unstable driving experience.
- Increased Emissions: The vehicle may produce higher emissions than usual, which can be detected during emissions testing.
- Engine Misfires: The engine may misfire or run unevenly, causing vibrations and potential damage over time.
How to Fix P245D 2015 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the exact cause of the high voltage in the EGR Cooler Bypass Control Circuit.
- Inspect Wiring and Connectors: Check for any damaged or corroded wiring and connectors in the EGR system and repair or replace them as needed.
- Test EGR Valve and Cooler: Verify the functionality of the EGR valve and cooler to ensure they are operating correctly and replace any faulty components.
- Clear Codes and Reset ECM: Clear the trouble codes from the ECM and reset the system to see if the issue persists after repairs have been made.
- Perform Emissions Test: After completing the repairs, conduct an emissions test to confirm that the vehicle is now compliant with emissions standards.
Cost to Fix P245D 2015 Chevrolet Silverado
The typical repair costs for addressing the P245D code on a 2015 Chevrolet Silverado can range from $200 to $600, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the price of potential replacement parts such as the EGR valve, EGR cooler, wiring harness, and connectors, as well as the labor costs associated with diagnosing and repairing the problem. It's important to note that the actual cost of repairs can vary based on factors such as the location of the repair shop, the make and model of the vehicle, and the extent of the damage. Additionally, diagnostic time and labor rates at auto repair shops can range from $80 to $150 per hour, with rates potentially higher at dealerships or in metropolitan areas, and lower at independent shops. It's recommended to obtain quotes from local repair shops to get a more accurate estimate for addressing the P245D code on a 2015 Chevrolet Silverado.
