P0246 Code – What Does It Mean & How To Fix It

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.


We’ll start by understanding what the P0246 DTC code means in this area of auto diagnostics. The DTC, which serves as a tool for specific problems in the vehicle system, is an alphanumeric code. Specifically, P0246 is related to an issue with the Turbocharger Wastegate Solenoid A circuit.


The DTC code P0246 indicates that there’s a fault in the Turbocharger Wastegate solenoid A circuit, which is indicative of an increased signal than anticipated. The solenoid shall be responsible for controlling the wastegate that regulates the boost pressure of the turbocharger. The signal may cause performance problems as well as lower fuel efficiency when it exceeds the expected value.


Effective diagnosis and repair of the P0246 DTC code depend on an understanding of its possible causes. Typical reasons include:

  • Faulty Turbocharger Wastegate Solenoid: A malfunctioning solenoid, often due to wear and tear or electrical issues, can trigger this code by producing an excessively high signal.
  • Wiring or Connector Problems: Damaged wiring or connectors in the Turbocharger Wastegate Solenoid A Circuit can disrupt the solenoid’s function, leading to high signal readings.


The P0246 DTC code’s associated symptoms might help you locate the problem. Typical signs include:

  • Reduced engine power
  • Poor acceleration
  • Increased fuel consumption
  • Illuminated check engine light
  • Potential engine knocking or pinging noises


A methodical diagnostic procedure is required to identify the precise reason for the P0246 DTC code. Typically, this entails:

  • Code Scanning: Retrieve the code and look for similar codes by using an OBD-II scanner.
  • Visual inspection: Look for any obvious damage to the wiring and solenoid for the turbocharger’s wastegate.
  • Testing: Test the electrical circuit for the solenoid to find any problems.

Common mistakes

It’s critical to avoid typical errors throughout the diagnostic and repair processes:

  • Ignoring the examination: Ignoring the visual examination might result in ignoring evident problems.
  • Replacing Parts Unnecessarily: Moving the solenoid prematurely without thorough testing may not always be the source of the problem.

How serious is this?

The seriousness of the P0246 DTC code is dependent on how it’s dealt with. Failure to take care of it may result in lower engine performance, higher fuel consumption, and possible engine damage over time. In order to prevent further difficulties, it is essential that this problem be dealt with immediately.

What repairs can fix the codeS?

repair manuals

The right repairs may be made when the problem has been identified. The following repairs might be made, depending on the cause:

  • Replacing the Wastegate Solenoid for the Turbocharger
  • Replacing or repairing faulty connections or wiring

Related codes

In some cases, the P0246 DTC code may be accompanied by related codes, such as:

  • P0244: Turbocharger Wastegate Solenoid A Circuit High
  • P0245: Turbocharger Wastegate Solenoid A Circuit Low
  • P0247: Turbocharger Wastegate Solenoid B Circuit Low
  • P0248: Turbocharger Wastegate Solenoid B Circuit High

These related codes may provide additional information about the issue.


To conclude, DTC code P0246 represents problems within the Turbocharger Wastegate Solenoid A circuit that specifically signals high levels of signal. It is vital to understand its significance, cause, symptoms, and diagnosis process in order to be able to resolve it effectively. 

In order to maintain the optimal performance of your vehicle and avoid any further damage, you should contact this code as soon as possible. If you do not know how to diagnose or repair the problem on your own, consult with an expert.
