Loss of power in engine turbo appears okay

Cause would be either a shorted or broken wire, corroded connection, or a bad MAP sensor. The MAP sensor is located on a bracket on the heater housing under the hood and has a hose running to the intake spider. You want to check the wires connected to the sensor or the sensor itself..

po237 means turbocharger boost sensor A circuit low and map sensor voltage too low.sounds like an electrical problem to me
