I have to replace one of my oxygen sensors and I dont really want to buy it from the dealer ,to expensive
is it ok if I buy Bosch oxygen sensor?
and does anyone know how many wires there is on the oxygen sensor (97 maxima)

thanks

 

and one more question
Is it ok to clean the sensors with the carbon clenaer , anyone done this before? thanks

 

Nissan uses Bosch for the o2 sensors so as long as you get ones for the maxima doesnt matter were you get them and all our o2 sensors have 3 wires

i here some people use throttle body cleaner and others use break cleaner... i think as long as it doesnt have silicon in the cleaner it should be fine but i just replaced mine so i never tryied cleaning them

 

If you haven't replaced your O2 sensor yet you can clean it.
In fact, the easiesy way thay I have found to clean them is to start the car and spray an entire can of Gumout into the throttle body while running the engine at around 2000 rpm's.

It cleans a lot of other stuff at the same time..... then put a pint of Marvel mystery oil in your gas tank to relube your valves and upper cylinders.... helps injectors too!
