XC70 Fault code assistance

My V70 XC has come up with Code P0237 Turbocharger Boost Sensor A Circuit Low and

Code P0016 Crankshaft Position Camshaft Position Correlation Bank Sensor A

Anybody able to help with what process to follow to fix.


  • If its had a timing belt replaced recently then they messed up the cam timing, if you have no idea of history it may be loose/worn out.

    Boost pressure code is probably the turbo control solenoid which you can test with vida

  • Thanks , Yes timing belt changed by European garage in Mosman, but still goes OK, would you notice the difference.

  • The ecu will notice the difference as it doesn't take much to stuff it up, and ecu will pull timing and prevent vvti operation.

    Was it just a timing belt replacement or did they do front oil seals or camshaft vvti phasers/pulleys?

    As that will determine how far out the timing could be and potential issues

  • Not sure, only going by timing belt changed sticker.
