P0245 Fault Code

P0245 OBD-II Trouble Code Short Description

Turbocharger Wastegate Solenoid A Low

What does trouble code P0245 mean?

The P0245 fault code indicates that there is an issue with the turbocharger wastegate solenoid A circuit, specifically that the voltage level is below the manufacturer's specified range. The wastegate solenoid is responsible for controlling the pressure of the turbocharger by regulating the amount of exhaust gas flow that bypasses the turbine. If this solenoid is not functioning properly, the turbocharger may not be able to perform optimally, leading to reduced performance and potentially other issues.

The solution to this problem typically involves the inspection of the turbocharger wastegate solenoid wiring and connections for any signs of damage or corrosion. If no issues are found, the solenoid itself may need to be replaced. It's important to address this problem promptly as it could lead to engine damage if left unaddressed.


What are the symptoms of the P0245 code?

Here are some possible symptoms of P0245 fault code:

  • Check Engine Light (CEL) will illuminate
  • Reduced engine performance and power
  • Turbocharger may not be engaging properly or not engaging at all
  • Engine may produce a hissing or whistling sound
  • Fuel economy may be affected


What causes the P0245 code?

P0245 fault code is caused by an issue with the wastegate solenoid in the turbocharger system. This solenoid is responsible for controlling the flow of exhaust gases that operate the turbocharger wastegate. When it fails or operates at a low voltage, the turbocharger system may not function correctly, leading to a decrease in engine performance and fuel economy. Possible causes of this fault code include a faulty wastegate solenoid, damaged or clogged vacuum lines, and wiring issues. To fix this issue, technicians may need to test and replace the wastegate solenoid, inspect and clean the vacuum lines, and check the wiring harness for any breaks or faults.

Possible Solutions

How to fix P0245?

The P0245 fault code refers to a problem with the turbocharger wastegate solenoid A. This means that the solenoid is not functioning properly, resulting in the wastegate not opening or closing as it should. This can lead to issues with the turbocharger and affect the overall performance of the vehicle.

Here are some possible solutions to fix this fault code:

  1. Check the wiring and connections - Make sure that the wiring and connections to the wastegate solenoid are intact and free from any damage or corrosion. Repair or replace any damaged parts.

  2. Replace the wastegate solenoid - If the wiring and connections are fine, then the problem may be with the solenoid itself. Replace the faulty solenoid with a new one.

  3. Check the turbocharger - If the turbocharger is not working properly, it can also cause issues with the wastegate solenoid. Have the turbocharger checked by a professional mechanic and repair or replace it as needed.

  4. Clear the fault code - After making the necessary repairs, clear the fault code and test drive the vehicle to see if the issue has been resolved.

If you are unsure of how to fix this problem, it is best to have it checked by a professional mechanic to avoid causing further damage to the vehicle.
