How to reset check engine light?


First replace the bank 2 sensor 1 O2 sensor. p0051 is that sensor heater circuit. These codes are always the O2 sensor, unless you see the wires are melted against the exhaust manifold. Once replaced the light will eventually go out. A code reader or scanner will turn it off.

Check engine light came on. scan said was O2 sensor. replaced O2. after trying to reset computer using scanner and disconnecting battery terminal, check engine comes back on after driving a few. code


The problem has to be fixed first.
The code probably did not say "replace sensor" but rather that the signal from the sensor was out of range.
The real problem could be the fuel system or other things.
What is the actual trouble code and vehicle info ?

If you replace the o2 sensor and that is the problem of why the check engine light is on then yes it will reset on its own. this will take a few days of driving due to the computer running all its tests and all passing then light will shut off.
the code you have is for a bad o2 sensor or wiring to it, there are a couple of o2 sensors, this code is for the rear o2 sensor.

My SERVICE ENGINE SOON light came onAGAIN!


Disconnecting the battery should reset it but I would bet that the light will come back on. I would have a auto parts store read the error code for you. They can also reset it. There are two o2 sensors on this car one on the manifold and one down stream from the converter. If you are getting an o2 error code it could also be the converter.

Check engine came on I replaced the o2 sensor. check engine light


You need to know what codes you have stored
Your O2 Sensor, may not be the problem,even though you get an O2 Code. That may just be the symptom
