I need to replace my front left bank o2 sensor and my knock sensor. Does anyone know where there located and where is the cheapest place to get them? What will happen if I drive with those sensor's blown?

 

Your car will implode with you in it ... and you will not live ..

Read the stickys please. It's ALL in there. Nothing bad will happen besides bad gas mileage/poor performance, there's a lot of info in the stickys, i.e. it might be one or the other sensor or jsut the O2, so read the stickys please please ....

 

0303 is the O2 sensor on the front bank. The KS is located inbetween the V below the intake manifold.

 

that o2 sensor is the one furthest forward on the y

 

Where can I get a cheap one?

forgot the "S"

Do I need to get both o2 sensor's?

 

i would probably go ahead and replace all three, as the others will probably go bad soon as well.

 

Is it bad to replace one at a time?

 

No its not but you may still get the code after replacing only one.

 

It said only one was gone. What should I do first the knock or the o2?

 

What should I get first?

 

I reset the codes and my light hasn't come back on since. Should I still replace the o2?

 

check to see if your knock sensor is working or not. The instructions are in the FAQ on hwo to check the sensor with a voltmeter.

Then, you better jump on this deal for 79 shipped becaus that's the cheapest i've seen yet and it's an OEM sensor from Pinnacle Nissan.

I am talking about the code for the o2.
