it is false economy to do that. the sensor is probably gone too,or on its way out. buy a new sensor. it will pay for itself in the long run.
Take it to the dealership.... Its real simple take the car jack it up take off the housing cover where the oxygen sensor is at then un plug the sensor, and replace...
You need to take a wrench to loosen the oxygen sensor, then you will need to disconnect the cord. Once you have done that you will then pull out the old oxygen sensor.
the oxygen sensor or 02 sensor is usually located on you headers it should take a 5/8 wrench it will have two wires coming off of it.
you take it to the people to fix it.
the oxygen sensor is on the exhaust manifold, to get to it you will need to take off the air intake box under the hood...you will see the sensor sticking out the manifold in plain view, against the radiator
You need to pull the code. Don't take a chance.
you gotta take the old one out first
Your best bet, if you dont know, take your car into a certified Nissan Dealership. That way you dont mess your car up as you try to find/fix it. Most of the time the o2 sensor issues arent a HUGE deal. but it is recommended that you take it in as soon as possible to be on the safe side
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
It's in back of the engine. Look for where the exhaust pipe reaches the engine and you'll see a wire coming out of it. That's where the oxygen sensor is. I think you have to take the heatshield off to repair it.
That means its junk take it to your near by junk yard That means its junk take it to your near by junk yard
