Can I replace an o2 sensor myself?
In general, assuming a mechanic charges $100 an hour for labor the typical bill to replace an sensor can be around $200 – assuming $100 for labor and $100 for the actual oxygen sensor. By doing the repair yourself, you can bring the cost down to only $200.
What happens when the 02 sensor goes bad?
If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off. If a bad oxygen sensor disrupts the air to fuel ratio mixture, or too much fuel is injected into the engine, your vehicle’s gas mileage will be reduced.
Can I drive my car with a faulty oxygen sensor?
In summary, yes, you can drive with a faulty O2 sensor. But you’ll want to change it immediately, because otherwise, you’ll be spending more money on fuel and you risk having to spend more on a new catalytic converter as well.
Should I replace all o2 sensors at once?
O2 sensors are a “wear item” and are recommended to be replaced every 75k mi. (if I remember correctly, check the FSM). Consider them part of a really proper tune-up regimen. Simply put, they are providing one set of input for your fuel injection system so it can manage things optimally.5 мая 2009 г.

How do I know if I have a bad o2 sensor or catalytic converter?
To the original question: The only way the ECU knows a cat is bad by the readings it get from the O2 sensors. A bad O2 sensor will indicate that the catalytic converter is bad. If the code indicates a bad cat…then further tests need to be run to determine if it’s a bad O2 sensor or a bad cat.

Are Bank 1 and Bank 2 o2 sensors the same?
Therefore, in an in-line 4-cylinder engine, the term “Bank 1, Sensor 1” simply refers to the front oxygen sensor. “Bank 1, Sensor 2” is the rear oxygen sensor. A V6 or V8 engine has two banks (or two parts of that “V”). Usually, the bank that contains the cylinder number 1 is called “Bank 1.”
