I have my old o2 sensor out and I'm trying to figure out how to splice this into a universal Bosch 4 wire sensor. The problem is the old o2 sensor has 5 wires, gray, black, white, red, and yellow and the Bosch has 4 wires, 2 whites one gray one black. So what goes with what? Thanks in advance

 

a 4 wire o2 wont work in the place of a 5 wire o2 because they ssre not the same, 4 wire is a narrow band sensor and 5 wire is a wideband sensor.

 

Damn. Makes sense though. It's weird at auto zone they have the 2wd version which is my car, under the narrowband version. The awd is wideband. Weird

 

This is a good example why I bought mine from Nissan....^....no issues....Gary

 

You bought the o2 sensor from Nissan?

 

check your pm hockey!!

 

hockey did u get the o2 sensor?

 

Yeah man I got it. Its weird though because I replaced the o2 sensor that I was getting a low, (3V) reading with the new one and its still 3v? Who knows, check engine light hasnt came on yet but we will see lol.
