P0247 Turbocharger Wastegate Solenoid A High

Have you ever heard a weird whistling sound coming from your car’s engine? It might be a sign of a turbocharger wastegate solenoid failure. This is a common issue in turbocharged engines, and it can cause a lot of problems if left untreated. In this article, we will delve into the details of the P0247 code, its causes, symptoms, and how to fix it.

What is the P0247 code?

The P0247 code is a generic powertrain code that indicates a problem with the turbocharger wastegate solenoid A. The wastegate solenoid is responsible for controlling the pressure of the exhaust gases that enter the turbocharger. If the solenoid fails, it can cause the turbocharger to overboost or underboost, which can lead to engine damage.

Causes of the P0247 code

There are many possible causes of the P0247 code, including:

1. A faulty wastegate solenoid – This is the most common cause of the P0247 code. The solenoid can fail due to wear and tear, electrical issues, or mechanical damage.
2. Wiring problems – The wiring that connects the wastegate solenoid to the engine control module (ECM) can become damaged, which can cause the solenoid to malfunction.
3. ECM problems – The ECM is responsible for controlling the wastegate solenoid. If the ECM fails, it can cause the solenoid to malfunction.

Symptoms of the P0247 code

The symptoms of the P0247 code can vary depending on the severity of the problem. Some common symptoms include:

1. A whistling sound from the engine – This is caused by the air escaping from the turbocharger due to the wastegate not opening or closing properly.
2. Loss of power – The engine may feel sluggish or have a lack of power, especially at higher speeds.
3. Check engine light – The check engine light will illuminate on the dashboard, indicating a problem with the engine.

How to fix the P0247 code

Fixing the P0247 code depends on the underlying cause of the problem. Here are some possible solutions:

1. Replace the wastegate solenoid – If the wastegate solenoid is faulty, it will need to be replaced. This is a relatively easy and inexpensive fix.
2. Check and repair wiring – If the wiring that connects the solenoid to the ECM is damaged, it will need to be repaired or replaced.
3. Replace the ECM – If the ECM is faulty, it will need to be replaced. This is a more expensive fix, but it is necessary if the ECM is the root cause of the problem.

Conclusion

The P0247 code is a common issue in turbocharged engines, and it can cause a lot of problems if left untreated. If you notice any of the symptoms mentioned above, it is important to take your car to a mechanic as soon as possible to diagnose and repair the issue. Regular maintenance can also help prevent wastegate solenoid failure, so be sure to keep your car’s engine in good shape.

FAQs

1. What is a wastegate solenoid?
   A wastegate solenoid is a component of a turbocharged engine that controls the pressure of the exhaust gases that enter the turbocharger.
2. How does a wastegate solenoid work?
   The wastegate solenoid is controlled by the engine control module (ECM). It opens and closes the wastegate valve, which controls the pressure of the exhaust gases that enter the turbocharger.
3. What causes wastegate solenoid failure?
   Wastegate solenoid failure can be caused by wear and tear, electrical issues, or mechanical damage.
4. Can I drive with a P0247 code?
   It is not recommended to drive with a P0247 code as it can cause a loss of power and engine damage.
5. How much does it cost to fix a P0247 code?
   The cost of fixing a P0247 code can vary depending on the underlying cause of the problem. Replacing the wastegate solenoid is a relatively easy and inexpensive fix, while replacing the ECM can be more expensive.
