This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a part of the car that helps control pollution. It's like a switch isn't working right, and it affects how the car cleans the air before it leaves the exhaust.
The EGR (Exhaust Gas Recirculation) cooler bypass control circuit is responsible for regulating the flow of exhaust gases to the cooler. An open circuit means there is a break or disconnection in the electrical circuit.
The P248E code indicates that the engine control module (ECM) has detected an open or faulty circuit in the EGR cooler bypass control for Bank 2. This can affect the vehicle's emissions by not properly cooling or bypassing the exhaust gases as intended.
• Check Engine Light is on
• Reduced engine performance
• Increased emissions
• Faulty EGR cooler bypass valve
• Damaged or corroded wiring or connectors
• Faulty ECM
EGR: Exhaust Gas Recirculation
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the EGR cooler bypass valve for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the EGR cooler bypass valve if faulty.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance checks
• Keep electrical connections clean and secure
• Use quality fuel to reduce emissions
Sensor Issue
• Have the vehicle inspected by a professional mechanic.
• Avoid driving long distances until the issue is resolved.
Check with your vehicle manufacturer for specific warranty coverage related to emissions control components.
This code has become more common with the introduction of stricter emissions standards and more complex EGR systems.
Moderate – Addressing this issue promptly can prevent further emissions-related problems.
Driving with a malfunctioning emissions system can lead to increased pollution and may not comply with local emissions regulations.
• Engine at operating temperature
• Vehicle running at idle
The EGR cooler bypass valve is typically located near the engine, connected to the EGR cooler and exhaust system.
Q: Can I drive my car with a P248E code?
A: It's best to have it checked as soon as possible to avoid potential emissions issues.
Q: What happens if I ignore the P248E code?
A: Ignoring the code can lead to increased emissions and possible engine performance issues.
