What Does P0164 Mean? OBD-II Code Decreased engine performance is defined as a O2 Sensor Circuit High Voltage The purpose of the oxygen sensor is to measure the oxygen content in the exhaust gases after they leave the combustion process of the engine. This information is critical to the PCM's ability to maintain efficient fuel economy. When the PCM detects a failure of the sensor or the information received from the sensor, it will set code P0164. engine code P0164P0164 fixobd P0164dtc P0164obd code P0164obd2 P0164P0164 car codediagnostic code P0164car code P0164check engine code P0164fehlercode P0164P0164 fiatcodigo P0164codigo falla P0164P0164 kody b??dówcodigo de falla P0164 What are the common causes of P0164 ? Trouble code P0164 sets when the engine control module detects high voltage on the oxygen sensor circuit for bank 2 sensor 3 for too long. Generally, a oxygen sensor’s voltage will vary up and down. The first sensor in the exhaust varies voltage very quickly and the voltage variance is greater. The second and third sensor varies slower and the voltage variance is smaller due to the catalyst in the exhaust. What are the symptoms of P0164 ? It does one good to note that the HO2S have nothing at all to do with fuel trim and are used only to verify TWC function, though FT problems, such as those caused by fuel pressure or misfiring cylinders, could skew HO2S readings, perhaps even set TWC or HO2S DTCs, but these would not result in circuit DTCs. Most of the time, as the TWC is not critical to engine function, but simply an emissions-control device, you will not notice anything other than the MIL. How do you troubleshoot P0164 ? Like the all engines, the car engine system employs specially developed hydraulic lifters (known as switching roller followers) for the P0164 code intake and exhaust valves. The lifters can be collapsed by disengaging an internal locking pin. The locking pin is disengaged using solenoids to alter oil pressure fed into the lifter.
