So is it possible for all 3, 2000 maxima fed spec o2 sensors to go at same time?

Changed seloid pack in tranny to get check engine light off. idk 1 to 2 weeks engine light back on w above codes.

If all 3 bad and not in error where do you guys buy new from? Will be checking oem after work today but just guessing even with my boys discount gonna be crazy expensive.

Thanks in advance to any that can help

 

Exhaust leak towards the front of the car can throw o2 codes. That's for 2 sensors tho not three

 

Just went with the oem front 2. Denso were about 100 each. With my boy that works at nissan got oem for 150 each. Figured took 130k for oem failure so I'll stick to oem. No check engine light as of now. Hopefully I got it fixed and will stay off.

Owned car since new (2000 kicked out early in 99) and always maintained so figured pretty good chance I'll see the 260k on this car and still have it. Never getting rid of it. Ever lol

Will post again if check engine comes back on. Hopefully not, and I got it
