P0247 Fault Code

Turbocharger Wastegate Solenoid B Malfunction

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0247 fault code indicates a problem with the turbocharger wastegate solenoid B circuit. The wastegate solenoid controls the flow of exhaust gases that drive the turbocharger. If the solenoid circuit has malfunctioned, the turbocharger may not work correctly, resulting in reduced engine power, poor acceleration, and possible engine damage.

To resolve this issue, the first step is to check the wastegate solenoid and its wiring for damage or corrosion. If you find any damage, you will need to replace the solenoid or repair the wiring. In some cases, you may also need to replace the turbocharger.

It is essential to address this issue promptly to avoid severe damage to your engine. If you are not comfortable diagnosing or repairing the issue yourself, it is best to have a professional mechanic take a look.

What are the symptoms of the P0247 code?

Symptoms of P0247 fault code on cars may include:

• Check Engine Light (CEL) or Malfunction Indicator Lamp (MIL) will illuminate on the dashboard.
• Reduced power or acceleration especially when under load or going uphill.
• Turbocharger may not engage or produce boost pressure.
• Increased fuel consumption.
• Engine may run rough or stall.

It is important to address this issue as soon as possible to prevent further damage to the turbocharger and engine. A certified mechanic can diagnose and repair the issue.

What causes the P0247 code?

The P0247 fault code on cars is caused by a malfunction in the turbocharger wastegate solenoid "B." This solenoid is responsible for controlling the pressure of the turbocharger wastegate, which regulates the amount of exhaust gases that enter the turbine and control boost pressure. A malfunction in this solenoid can cause various symptoms, including a lack of power, a rough idle, and even engine stalling. It is usually caused by electrical or mechanical issues, such as a faulty solenoid, damaged wiring, or physical damage to the wastegate actuator.

How to fix P0247?

To fix the P0247 fault code, follow these steps:

1. Check the wiring and connectors of the turbocharger wastegate solenoid B. Make sure they are properly connected and not corroded or damaged. Repair or replace any damaged wiring or connectors as needed.

2. Test the wastegate solenoid B using a multimeter to check for proper resistance. The resistance value should be within the manufacturer's specifications. Replace the solenoid if it fails the test.

3. Check the vacuum hoses connected to the wastegate solenoid B for damage or leaks. Replace any damaged hoses and tighten any loose connections.

4. Inspect the turbocharger wastegate valve for proper operation and smooth movement without any binding or restriction. A faulty wastegate valve may cause the solenoid to malfunction.

5. Clear the fault codes using a diagnostic scanner and test drive the vehicle to see if the P0247 code returns. If the code reappears, further diagnosis may be needed to determine the root cause of the problem.
