1 vehicles · 1 makes · $80-$3,500 repair
Most Reported On
P0237 is an OBD-II diagnostic trouble code meaning “Turbocharger Boost Sensor A Circuit Low.” This code sets when the turbocharger (or supercharger) boost pressure sensor 'A' reports a voltage that's lower than its normal operating range. That sensor measures how much boost the engine is producing so the computer can correctly control fueling, timing, and the wastegate. A signal that's too low usually means a wiring fault, short to ground, or a failed sensor rather than an actual loss of boost, and the engine may run with reduced power for protection. It generally points to a problem in the sensor or its circuit. This code is most commonly reported on 2015-2024 Ford Transit, with repair costs ranging from $80 to $3,500.
