Order of inspection
P0242 Turbocharger/Supercharger Boost Sensor B Circuit High Medium
The P0242 code means the signal from turbo boost pressure sensor B went above its maximum value, usually from a lost sensor ground, an open wire or a short to voltage. It causes a loss of power because the computer limits the turbo. Check the ground and the connector first.
