I went to auto zone to get some o2 sensors for a 2003 maxima and it was the green harness and dark blue harness o2 sensors and it was bosch 15525 and 15521 on autozone.com and they seem to be too short in wire length to reach the engine harness anyone can help me out here with the correct o2 sensors

 

First of all you better off using OEM genuine Nissan 02 sensor, even a used but working O2 sensor. By the way which 02 sensor you want to replace, the primary or the secondary? What error code you have on the car?

 

OEM is no different than any other.....you guys kill me with this stuff. 1-9mv is 1-9mv no matter what name is on the box. Bosch is a Bosch is a Bosch.


What codes, if it's the rear, I could make a dual sim....

 

He did Bosch is OEM

 

The car is a friend of mine and he got it with no engine and its missing 2 of the oxygen sensors but I figured it out tho thanks for the help

 

Bosh is oem
