This summary uses the existing diagnostic information shown in full below.
Your car has a system that helps reduce pollution, and one part of it isn't working right. It's like a switch that isn't turning on when it should.
This code indicates that the EGR cooler bypass control circuit is open or not functioning properly on bank 1 of the engine.
The Exhaust Gas Recirculation (EGR) system helps reduce nitrogen oxide emissions by recirculating a portion of the exhaust gases back into the engine cylinders. The EGR cooler bypass valve is used to control the flow of exhaust gases through the EGR cooler. If the control circuit for this valve is open or not functioning, the system cannot properly regulate the exhaust gas temperature.
• Check Engine Light is on
• Reduced engine performance
• Increased emissions
• Faulty EGR cooler bypass valve
• Damaged or corroded wiring or connectors
• Faulty EGR bypass valve control solenoid
EGR: Exhaust Gas Recirculation
Bypass Valve: A valve that redirects flow around a component
• Scan the vehicle for codes and freeze frame data
• Inspect the wiring and connectors for damage or corrosion
• Test the EGR cooler bypass valve for proper operation
• Replace the EGR cooler bypass valve if faulty
• Repair or replace damaged wiring or connectors
• Replace the EGR bypass valve control solenoid if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regular maintenance of the EGR system
• Use quality fuel to reduce carbon buildup
• Inspect wiring and connectors periodically
Sensor Issue
• Address the issue promptly to avoid further damage
• Consult a professional mechanic if unsure
• Do not ignore the Check Engine Light
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
This code has been associated with issues in diesel engines where EGR systems are more complex.
Moderate – Should be addressed soon to prevent increased emissions and potential engine performance issues.
Driving with a malfunctioning EGR system may result in failing emissions tests and increased pollution.
• Engine at operating temperature
• Vehicle in closed loop operation
The EGR cooler bypass valve is typically located near the EGR cooler, which is mounted on the engine.
Q: Can I drive with a P245A code?
A: It's not recommended as it can lead to increased emissions and potential engine performance issues.
Q: How does the EGR system affect my car?
A: The EGR system helps reduce emissions by recirculating exhaust gases back into the engine.
