P245D 2016 GMC Sierra Code - Exhaust Gas Recirculation Cooler Bypass Control Circuit High Voltage
Quick Answer
The P245D diagnostic trouble code (DTC) for a 2016 GMC Sierra specifically relates to the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit registering high voltage. Common causes include Faulty EGR Cooler Bypass Valve: The bypass valve may be stuck open or closed, causing high voltage in the circuit, Wiring Issues: Corroded or damaged wiring connections can disrupt the electrical signal to the EGR cooler bypass valve, Malfunctioning EGR Cooler: A defective EGR cooler can cause the system to operate improperly, leading to high voltage in the circuit. 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 2016 GMC Sierra Description
The P245D diagnostic trouble code (DTC) for a 2016 GMC Sierra specifically relates to the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit registering high voltage. The EGR system in a vehicle is responsible for recirculating a portion of the exhaust gases back into the engine cylinders to reduce emissions of nitrogen oxides (NOx). The EGR cooler helps lower the temperature of the recirculated exhaust gases before they are reintroduced into the engine, improving combustion efficiency and reducing emissions.
Common Causes of P245D 2016 GMC Sierra
- Faulty EGR Cooler Bypass Valve: The bypass valve may be stuck open or closed, causing high voltage in the circuit.
- Wiring Issues: Corroded or damaged wiring connections can disrupt the electrical signal to the EGR cooler bypass valve.
- Malfunctioning EGR Cooler: A defective EGR cooler can cause the system to operate improperly, leading to high voltage in the circuit.
- ECM Malfunction: Issues with the engine control module can result in incorrect signals being sent to the EGR system components.
Symptoms of P245D 2016 GMC Sierra
- 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 Engine Performance: The vehicle may experience a decrease in power and acceleration due to the improper operation of the EGR system.
- Increased Emissions: High levels of NOx emissions may be detected during emissions testing as a result of the malfunctioning EGR system.
- Rough Idle: The engine may idle roughly or inconsistently due to the EGR system not functioning correctly.
- Poor Fuel Efficiency: A malfunctioning EGR system can lead to decreased fuel efficiency, resulting in more frequent refueling.
How to Fix P245D 2016 GMC Sierra
- Diagnostic Scan: Use an OBD-II scanner to retrieve the specific DTC and identify the source of the issue.
- Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Test EGR Cooler Bypass Valve: Test the bypass valve to ensure it is functioning properly. Replace if faulty.
- Check EGR Cooler: Inspect the EGR cooler for any leaks or blockages that may be affecting its operation. Replace if necessary.
- Reset ECM: Clear the DTC and reset the ECM to ensure the issue has been resolved.
Cost to Fix P245D 2016 GMC Sierra
The typical repair costs for addressing a P245D code on a 2016 GMC Sierra can vary depending on the specific cause of the issue. In general, parts for the EGR system, such as the bypass valve or cooler, can range from $100 to $500. Labor costs at an auto repair shop can add an additional $100 to $300 to the total repair bill. Overall, the total cost for resolving this issue may fall within the range of $200 to $800, including parts and labor. It's important to note that actual repair costs can fluctuate based on factors such as location, vehicle make and model, and the extent of the repairs needed. It's recommended to obtain quotes from local auto repair shops to get a more accurate estimate for this repair.
