This summary uses the existing diagnostic information shown in full below.
This code means that a part in your car that helps cool the air going into the engine is not moving like it should. It's like a door that is stuck and can't open or close properly.
The code is triggered when the Engine Control Module (ECM) detects that the charge air cooler bypass valve is not operating as expected, meaning it is stuck in one position.
The charge air cooler bypass valve is responsible for regulating the flow of air through the charge air cooler. If this valve gets stuck, it can affect the engine's performance by not allowing the proper amount of cooled air to enter the engine. This can lead to increased engine temperatures and reduced efficiency.
• Check Engine Light illuminated
• Reduced engine performance
• Poor fuel economy
• Engine overheating
• Faulty bypass valve
• Wiring issues or poor electrical connections
• Mechanical obstruction in the valve
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
Bypass Valve: A valve that controls the flow of air around the charge air cooler
• Use an OBD-II scanner to confirm the code.
• Inspect the bypass valve for physical damage or obstructions.
• Check the wiring and connections to the valve.
• Test the valve operation with a multimeter or diagnostic tool.
• Replace the faulty bypass valve.
• Repair or replace damaged wiring or connectors.
• Clear any obstructions in the valve mechanism.
• Update or reprogram the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdrivers
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram 1500
• Regular maintenance and inspection of the air intake system.
• Ensure proper electrical connections.
• Avoid driving through deep water that could damage components.
Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regularly check for any unusual engine noises or performance issues.
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
This code has been more prevalent in turbocharged engines where the charge air cooler is more commonly used.
Moderate – It is important to address this issue to prevent further engine performance problems.
Driving with a malfunctioning air cooler bypass can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle in a safe, static position
The charge air cooler bypass valve is typically located near the intercooler or turbocharger in the engine bay.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to reduced engine performance, increased fuel consumption, and potential engine damage.
Q: Can I drive with this code?
A: While the vehicle may still be drivable, it is not recommended to drive for extended periods without addressing the issue.
