Order of inspection
P0237 Turbocharger/Supercharger Boost Sensor A Circuit Low Medium
The P0237 code means the signal from turbo boost pressure sensor A dropped below its minimum value, usually from a short to ground or a missing 5 volt reference. It causes a loss of power because the computer limits the turbo. Check the wiring and the reference voltage first.
