Where is the second sensor located on the '99 max? if anyone knows of a diagram or a very good answer that would be most helpful. the reason why i am asking is because i need to replace that one cause it reads high voltage or something. anyone have anything?

 

what kind of sensor?

 

No ****

 

The rear heated oxygen sensor (Rear HO2S) is after the catalyst. Look under the car and you can see it.

 

oh...i thought you meant the one in the clock that senses seconds.

 

Are you Fed or Cali spec?

 

i think cali, thats with no O2 sensor between the cat and resonator pipe right? cause i dont have a O2 sensor between those two. i only have 2 on my y-pipe and 1 on each exhaust manifold. i need to replace the second one which ever one that is. all it says on the description of the code is number 2 O2 sensor high voltage. all i want to know is where the second O2 sensor its talking about where it is located.
