    P0237 would indicate a short to ground with the intake boost pressure sensor A input. This shorted boost sensor circuit won't be able to calculate the pressure to the PCM which would cause a lack of power in general (especially when accelerating). 

    Check the boost sensor connector for full connection and for corrosion on the pins and also cabling and look for a visible short. This could be the issue but also check for a defective boost sensor or a defective turbo or a faulty PCM.

     

    Hope this helps 🙂
