The boost pressure in the intake can give you a lot of power.Verify the connections to the sensor are secure and not leaking, kinked or cracked.Check the boost pressure sensor hose for obstructions or kinks.Scans codes and documents the freeze frame data in order to verify the problemĬlears the codes to verify whether the concern comes backĬhecks the operation of the boost pressure sensor compared to the MAP sensorĬhecks the turbo boost sensor for blockage of the sensor port, or boost sensor hose or lineĬhecks the turbo boost sensor connector for loose or corroded pinsĬommon mistakes when diagnosing the P0236 code?įollow these simple guidelines to prevent misdiagnosis: How does a mechanic diagnose the P0236 code? The engine may lack some power during acceleration if the boost sensor is failing to register the correct amount of boost pressure The engine turbo boost may be turned off by the ECM and the engine will lack power The Check Engine Light will be illuminated and the code set The turbo boost pressure sensor A is slow to respond to changing pressure due to deterioration with age The turbo boost pressure sensor A is contaminated or clogged with debris or carbon deposits The turbo boost pressure sensor does not correlate the same reading with the MAP or BARO sensors at engine idle or when the key is on and the engine is off. P0236 is an OBD-II generic code that is triggered when the Engine Control Module (ECM) detects the intake boost pressure sensor A input circuit range or performance is out of specifications when compared to the manifold pressure sensor (MAP) or the barometric pressure sensor (BARO) at idle and with the key on, engine off, before starting.
