What Does P0154 Mean? The oxygen sensor’s purpose is to send information to the power control module (PCM) regarding the amount of oxygen that exists in the exhaust. The power control module uses that information to regulate the amount of fuel that is released into the engine. The goal of which, is to maintain the proper ratio of air and fuel. When the oxygen sensor is working properly, it will rapidly switch from high voltage (rich exhaust) to low voltage (lean exhaust). If the oxygen sensor fails to switch back and forth or gets stuck either the high voltage or low voltage, this will result in the power control module (PCM) storing the P0154 trouble code, and the vehicle’s Check Engine Light will come on. engine code P0154P0154 fixobd P0154dtc P0154obd code P0154obd2 P0154P0154 car codediagnostic code P0154car code P0154check engine code P0154fehlercode P0154P0154 fiatcodigo P0154codigo falla P0154P0154 kody b??dówcodigo de falla P0154What are the common causes of P0154 ? Possible causes include a faulty oxygen sensor, faulty electrical connector at the oxygen sensor, faulty or shorted wiring in the oxygen sensor circuit, a blown fuse for the oxygen sensor (if applicable), low or excessive fuel pressure, a vacuum leak on the engine, excessive exhaust leaks, or a faulty PCM. PCM failure is rare. What are the symptoms of P0154 ? Check Engine Light will illuminate In many cases, no abnormal symptoms may be noticed In some cases, the engine may hesitate during acceleration Poor fuel economy How do you troubleshoot P0154 ? Deactivation of cylinders is achieved by releasing a synchroniser pin that normally interlocks the cam follower and rocker arms. P0154 code resolves the synchroniser pin is released using hydraulic pressure which is controlled by a dedicated solenoid.
