• Noticeable reduction in power when accelerating
• A hissing noise coming from the engine
• More frequent turbocharger spooling sound
• Reduced air pressure in the intake manifold

What causes the P024A code?

The P024A error code refers to the charge air cooler bypass control circuit having a range or performance issue. Some common causes for this fault code include:

• Faulty charge air cooler bypass valve
• Dirty or clogged charge air cooler
• Malfunctioning charge air temperature sensor
• Wiring issues, such as a short circuit or open circuit
• Failed electronic control module (ECM)

If you are experiencing this error code, it is recommended to take your vehicle to a qualified mechanic to diagnose and repair the root issue.

How to fix P024A?

The P024A fault code indicates that there is an issue with the Charge Air Cooler Bypass Control A Circuit. This could be due to a variety of reasons such as a faulty bypass valve, damaged wiring, or a problem with the control module. Here are some steps you can take to fix the issue:

1. Check the wiring: Check for any damaged, open or shorted wiring in the Charge Air Cooler Bypass Control circuit. Repair or replace any damaged wires as necessary.

2. Replace the bypass valve: If the wiring checks out, then the issue may be with the bypass valve itself. Replace the bypass valve and clear the fault code.

3. Check the control module: If both the wiring and the bypass valve are functioning properly, then the issue may be with the control module. Check the wiring going into the control module and ensure there are no opens or shorts. If the wiring checks out, then the control module may need to be replaced.

In any case, it is recommended to consult with a certified mechanic to diagnose and fix the issue correctly.
