How many knock sensors and O2 sensors have you replaced? How many miles are on your Maxima?

 

One knock sensor around 80,000.

 

Replaced one knock sensor and one rear O2 sensor. I have 87,500 miles.

 

1 knock sensor..Just passed 101K

 

i have 150k and i never had to replace any o2, or knock sensor... would it give me a check engine light if it went out? because i am getting bad mpg (12-13mpg) i did get a complete tune-up , new injecotrs, and coils.
:-(

 

Replaced one O2 sensor and one knock sensor. Check my sig.

 

Knock sensor by itself usually doesn't trip the light, I think O2 will...

 

I've replaced 1 knock sensor and i have to change my rear o2 sensor..112K miles

 

replace KS today @ 129,735 miles, No O2 sensor.
