P0237 code definition Turbocharger Boost Sensor A Circuit Low What the P0237 code means P0237 is an OBD-II generic code that is triggered when the Engine Control Module (ECM) detects the intake boost pressure sensor A input circuit low below specifications, indicating a short to ground. What causes the P0237 code? - The turbo boost pressure sensor internally shorted to ground - The turbo boost pressure sensor A connector is damaged, causing a short to ground - The turbo boost pressure sensor A wiring is shorted to ground between the sensor and the ECM What are the symptoms of the P0237 code? - The Check Engine Light will be illuminated and the code set - The engine turbo boost may be turned off by the ECM and the engine will lack power - The engine may lack some power during acceleration if the boost sensor circuit is shorted and cannot input the correct amount of boost pressure to the ECM. - I would first check for leaks in the turbo pressure pipes if they are all ok check the turbo pressure sensor and wiring to the sensor.
