Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

SOURCE: the check engine light is on the code is P0051

FIRST THING IS RESET THE CHECK ENGINE LIGHT AND SEE IF CODE RETURNS... RUN IT FOR A LITTLE TO MAKE SURE YOU DON'T HAVE BAD GAS.... IF IT STILL COMES ON REPLACE 02 SENSOR LOCATED IN THE EXHUAST PIPE.. THERE SHOULD BE TWO IN PIPE YOU WANT THE ONE CLOSEST TO THE END OF THE EXHUAST PIPE

SOURCE: oxygen sensor heater control circuit, low voltage

yes and also may make it run rough or lack power. the o2 sensors tell the computer how to make the engine run

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

All 4 O2 sensors failed at same time


No that is not possible. You either have lost power or ground to sensors or the system has a fuel control issue.

Check the relays and fuses for the H.E.G.O (heated oxygen sensors) for power and function.

P0037 code subaru outback I have replaced the cat and both o2 sensors and the same code comes up


I'm sorry you spent that money if this was the original code.

The code means one of the O2 sensors has a faulty heater or the power circuit for the heater is bad. The sensor is not heating up as fast as it should. Since you have replaced the sensor you would need to check the power circuit for the heater.

P0037 SUBARU Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).

In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.

The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

Yes the O2 sensor preheater problem will turn on the VSC light, see the complaint often, why? don't know
.P0031 TOYOTA - Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 1
In most cases the O2 being replaced cures the code but here is the full story.
Possible causes- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit open shorted to ground
- Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit poor electrical connection
- Faulty Air-Fuel Ratio (A/F) Sensor Bank 1 Sensor 1 circuit

- Faulty Engine Control Module (ECM)

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 Forums.com for you.

2001 Toyota 4 Runner has Trac off vsc trac and check engine light on what can cause this


When the computer detects certain faults it will set the check engine light on along with the other lights you've explained. I've seen this on many toyota SUV's. Usually the codes set are oxygen sensor related. There really is no relation between the oxygen sensors and the traction control system but for some reason it disables it and sets the warning lights on. Have the computer scanned for codes at a shop or at a parts store such as autozone for free.

P0057


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.
