check engine light

P0247 code definition

The P0247 code indicates that there is a turbocharger wastegate solenoid B malfunction.

What the P0247 code means

When the P0247 code appears on your vehicle, it means that the powertrain control module has found readings that are not normal for the turbocharger wastegate solenoid B. This could indicate some type of malfunction.

What causes the P0247 code?

The following are the most common causes for the P0247 code.

  • Faulty wastegate solenoid
  • Shorted or open wiring in the wastegate solenoid circuit
  • Loose connectors in the wastegate solenoid
  • Corroded connectors in the wastegate solenoid
  • Disconnected connectors in the wastegate solenoid

What are the symptoms of the P0247 code?

There can be a number of symptoms associated with the P0247 code. You may notice that the engine acceleration is reduced. The turbocharger might also make some sounds that it shouldn’t be making such as a rattling or a whining sound. The exhaust might be producing more smoke than usual. The spark plugs could be fouled, the temperature in the engine and/or the transmission could be higher than normal, and the vehicle’s engine may no longer perform as well as it should. Quite often, there will be other codes that accompany the P0247 code. These can include knock sensor codes, engine misfire codes, and other codes relating to the turbocharger.

How does a mechanic diagnose the P0247 code?

When a mechanic diagnoses the P0247 code, they will be using an OBD-II scanner. They simply connect the scanner to the vehicle’s onboard diagnostics computer and access the data that it has been storing. They can use the scanner to further diagnose the vehicle. The mechanics will also want to reset the code. They do this so they can then test the car to see if the code comes back. This helps them to rule out false positives and allows them to provide the proper diagnosis. They will also want to check out the entire turbocharger system to make sure that they do not miss anything.

Common mistakes when diagnosing the P0247 code

One of the most common mistakes when diagnosing the P0247 code is not diagnosing the entire wastegate system. It is important to diagnose the entire system so you can repair the proper part.

How serious is the P0247 code?

As evidenced by all of the potential symptoms that your vehicle could suffer, the P0247 code is very serious. It can have a severe effect on the performance of your vehicle. If this code is present, it is quite likely that there are other codes affecting your vehicle as well. It is very important that you take your vehicle to a qualified mechanic who can provide you with a proper diagnosis and make the repairs you need.

What repairs can fix the P0247 code?

The following are some of the repairs that could fix the P0247 code:

  • Check for loose, corroded, or disconnected connectors in the wastegate solenoid, and make repairs or replacements to them as needed.
  • Check for open or shorted wiring and make repairs.
  • They will then likely reset the code and test the vehicle again to see if the problem continues.
  • If the other options do not repair the vehicle and remove the code, they may need to replace the wastegate solenoid.

Additional comments for consideration regarding the P0247 code

The turbocharger system needs to be thoroughly examined to make sure that the mechanic takes care of all of the potential issues. As noted, the P0247 code is often accompanied by other codes. It is important to diagnose and take care of each of these codes in the proper order and to make the needed repairs. If you have been having issues with your vehicle, you do not want to suffer from continued performance issues. It’s important to work with a great mechanic.
