A p0057 code is related to the heater circuit voltage for the bank 2 sensor 2 Oxygen sensor. The PCM (computer) controls a heating element inside the O2 sensor that helps the sensor reach a high temp in order for the O2 to start working faster. It seems this circuit is not working, therefor the PCM alerts us by displaying a trouble code. In most cases, replacing the O2 repairs this code.

2007 Volvo S80 T6 3.2L OBD Code P0057 Bank 2 Sensor 2 won't clear and Code P0172 came back, have changed the oil diffuser cover and both O2 downstream sensors, need help ASAP

changed the wrong sensors
the code (p0057)refers to the heated oxygen sensor (HO2S) which is in the exhaust manifold before the cat converter
code p 0172 refers to system too rich bank bank 1===causes ---intake blocked ---EVAP canister purge valve --- fuel pressure---EGR systems ---injector/s---HO2S
If you replace the HO2S sensor/s then that will [robably fix all codes
the heated oxygen sensor reads the exhayst gas and reports to the ECM to adjust the air /fuel ratio to get the engine to run within parameters
when it is not working , it runs lean or rich

How do I fix P0300,P0301,P0303, P0305,P1313,P1316& P1646?2 weeks ago,codes were minus P1313&P1316 with P0057 added in.replaced bank2 downstream sensor,P0057 gone but 2 new codes popped up????

the engine managment system on this car treats each bank as 2 seperate engines bank 1 and bank 2 the fault codes you have got are emission related. diagnosis is not easy because the ecu will use the other bank to compensate and alter its fueling etc to reduce emissions. the only way to sort it out is to put it on suitable diagnostic equipment and monitor live data ie. lambda sensors/ catalyst efficiency hope this helps

Do know which sensor this is?

Is IT the oxygen sensor on the catalysator or the temperature sensor on the engine?

My check engine light is on in my Jaguar X-type 2003, and the car just failed the emission test. The code that they gave us was "P0057." What does this code mean?

P0057 Definition: O2 Sensor heater circuit low- 22
Probable causes:
1. Open or short circuit condition
2. Open fuse
3. Failed HO2S 11 (i.e., bad O2 Sensor).

Got this off the Jaguar for you.
