P245A 2016 GMC Sierra Code - Exhaust Gas Recirculation Cooler Bypass Control Circuit
Quick Answer
The P245A diagnostic trouble code (DTC) specifically relates to the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit in a 2016 GMC Sierra. Common causes include Faulty EGR Cooler Bypass Control Solenoid: The solenoid responsible for controlling the bypass of exhaust gases through the EGR cooler may be malfunctioning, Wiring Issues: Damaged or corroded wiring connections related to the EGR Cooler Bypass Control Circuit can cause the P245A code to trigger, EGR Cooler Bypass Valve Failure: The valve that regulates the flow of exhaust gases through the EGR cooler may be stuck or not functioning properly. 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 P245A 2016 GMC Sierra Description
The P245A diagnostic trouble code (DTC) specifically relates to the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit in a 2016 GMC Sierra. The EGR system in a vehicle is responsible for recirculating a portion of the exhaust gases back into the engine cylinders to reduce emissions and control combustion temperatures. The EGR cooler helps to lower the temperature of the recirculated exhaust gases before they are reintroduced into the engine.
Common Causes of P245A 2016 GMC Sierra
- Faulty EGR Cooler Bypass Control Solenoid: The solenoid responsible for controlling the bypass of exhaust gases through the EGR cooler may be malfunctioning.
- Wiring Issues: Damaged or corroded wiring connections related to the EGR Cooler Bypass Control Circuit can cause the P245A code to trigger.
- EGR Cooler Bypass Valve Failure: The valve that regulates the flow of exhaust gases through the EGR cooler may be stuck or not functioning properly.
- EGR Cooler Blockage: Build-up of carbon deposits or debris in the EGR cooler can obstruct the flow of exhaust gases and lead to circuit malfunctions.
Symptoms of P245A 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with the P245A code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The engine may experience a decrease in power and acceleration due to improper EGR system operation.
- Rough Idle: The vehicle may exhibit rough idling or stalling when the EGR system is not functioning correctly.
- Increased Emissions: A faulty EGR Cooler Bypass Control Circuit can lead to higher emissions output from the vehicle.
How to Fix P245A 2016 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the EGR Cooler Bypass Control Circuit components.
- Replace Faulty Components: Replace the faulty EGR Cooler Bypass Control Solenoid, wiring, or valve as needed to restore proper operation.
- Clean EGR Cooler: If blockages are found, clean the EGR cooler to ensure proper flow of exhaust gases.
- Clear DTC: Clear the DTC from the vehicle's memory using the scan tool after completing the repairs.
- Test Drive: Take the vehicle for a test drive to verify that the issue has been resolved and that the Check Engine Light does not reappear.
Cost to Fix P245A 2016 GMC Sierra
The typical repair costs for addressing the P245A code on a 2016 GMC Sierra can vary depending on the extent of the issue and the specific components that need to be replaced. In general, the parts required for this repair, such as the EGR Cooler Bypass Control Solenoid or valve, can range from $100 to $300. Labor costs at auto repair shops typically range from $80 to $150 per hour, and the total repair bill may amount to $300 to $600 or more, including parts and labor.

Frequently Asked Questions about P245A 2016 GMC Sierra Code
1. What does the OBDII code P245A mean on a 2016 GMC Sierra?
P245A indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit, which manages the bypass valve for the EGR cooler.
2. What are the common symptoms of code P245A on a 2016 GMC Sierra?
Symptoms may include a check engine light, reduced fuel efficiency, increased emissions, or loss of engine performance.
3. What causes the P245A code to appear on a 2016 GMC Sierra?
Common causes include a faulty EGR cooler bypass valve, wiring issues, a malfunctioning control module, or carbon buildup in the EGR system.
4. Can I drive my 2016 GMC Sierra with a P245A code?
While the vehicle may still be drivable, ignoring the issue can lead to reduced engine performance and potential damage to the EGR system over time.
5. How can I diagnose the P245A code on my 2016 GMC Sierra?
Start by using an OBDII scanner to confirm the code, then inspect the EGR bypass valve, wiring, and connectors for damage or carbon buildup.
6. How do I fix the P245A code on my 2016 GMC Sierra?
Repairs may include cleaning or replacing the EGR bypass valve, repairing damaged wiring, or updating/reprogramming the engine control module if necessary.
7. How much does it cost to repair a P245A code on a 2016 GMC Sierra?
Repair costs vary but typically range from $150 to $600, depending on whether parts like the EGR bypass valve need replacement.
8. Can a dirty EGR system cause the P245A code?
Yes, carbon buildup in the EGR system can cause the bypass valve to stick, triggering the code.
