I have a car that has over 200,000 miles on it and the service engine soon light keeps coming on. I have taken it to Auto Zone and they said it was the oxygen sensor. My question is it anything to be worried about because I don't want to be stuck on the side of the road. Thank you.

Please disregard the moronic comment about an O2 sensor burning raw gas. That is so far from correct I would kill my own son if he gave that answer.
Simply and without going into great detail, the oxygen sensor senses and reports electrically to the engine computer how much oxygen is in the exhaust stream. This allows the computer to determine how much fuel the engine needs to run at the proper air/fuel ratio. That being said;
1. No matter what Autozone wants you to believe, there is no code, and never has been that tells you you have a bad oxygen sensor. What a code does is tell you that there's a problem in a particular circuit or system that requires further diagnostics, in this case the O2 circuit.
2. A bad or even completely missing O2 sensor will not leave you stranded on the side of the road in and of itself. However, it could potentially cause you to develop a collapsed/clogged catalytic convertor which would potentially leave you stranded.

With a 4 cylinder engine, the code definition ought to have study: B1S1 (for the upstream sensor in charge for gas/air ratio monitoring) or B1S2 (for the sensor downstream of the catalytic converter, which only video exhibit contraptions that area). in case you replaced the front (S1) sensor and you nonetheless have a code for it, save your old sensor as there could be no longer something incorrect with it. If the code is for the O2 sensor heater, verify your fuses. If no longer, the code is probable a symptom of yet another undertaking, which contain a misfire, limited gas clear out or intake air leak. is this an identical code you purchased till now? Did you install an prompt-greater healthy replace or a accepted sensor that had to be configured on your honda's wiring connector?

The oxygen sensor is very important to the correct operation of the fuel injection system as answer #2 stated. The oxygen sensor is used to determine if the engine is running rich (not enough oxygen) or lean (too much oxygen). Many factors can cause this concern . It is advised to have your concern professionally diagnosed . Good luck.

How is your car running? The o2 sensor has to do with emissions. It will not leave you stuck on the side of the road. However if it starts affecting you fuel consumption and performance of the car you will have to get it replaced.

It screws into exhaust pipe and sends a signal to pcm in millivolts ranging from 100 mv to 950 mv depending on fuel mixture.Plays a important part in keeping fuel at a 14 to 1 ratio for gas mileage and emissons

The oxygen sensor will not make the car to brake down. But it will start to have a Strong gas smell if you do not replace it.

it screws down in your exhaust and it burns raw gas that your motor doesnt before it goes out the tailpipe.
