Code P245A 2014 GMC Sierra Description
The P245A diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit. The EGR system is responsible for recirculating a portion of the exhaust gas back into the intake manifold to reduce emissions and control combustion temperatures. The EGR cooler helps cool the recirculated exhaust gas before it enters the engine.
Common Causes of P245A 2014 GMC Sierra
- Faulty EGR Cooler Bypass Control Valve
- Wiring or electrical issues in the EGR system
- Carbon buildup in the EGR system
- Vacuum leaks in the EGR system
- Malfunctioning EGR temperature sensor
Symptoms of P245A 2014 GMC Sierra
- Check Engine Light illuminated on the dashboard
- Rough idling or stalling
- Reduced fuel efficiency
- Hesitation or lack of power during acceleration
- Increased emissions
How to Fix P245A 2014 GMC Sierra
- Diagnose the EGR system using a scan tool to confirm the P245A code and identify the specific component causing the issue.
- Inspect the EGR Cooler Bypass Control Valve, wiring, and connections for any visible damage or corrosion.
- Clean or replace the EGR Cooler Bypass Control Valve if it is faulty.
- Check and repair any wiring or electrical issues in the EGR system.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P245A 2014 GMC Sierra
