Hi everyone,
I used the search function to deal with a CEL that pulled code PO150 aka 0303. I realize that means my front O2 sensor. I am correct that my 1996 (non-CA) Maxima has three O2 sensors, the two in the front (before the cat) and one past the cat? Since one front O2 sensor is bad I figured I would just replace both. The question is are both front O2 sensors the exact same part, and part number? I went on rockauto.com and they list a direct-fit Bosch, but it seems the be the same part for the front one's.

When I did a search, one poster said something about the length of the wires being different for each front sensor? I want to go with direct-fit sensors, but I want to make sure I get the correct parts. oxygensensors.com has Walker brand O2's, and again it looks like both front's are the same? I think I will go with the $86.99 Bosch sensors from rockauto.com, since they are OEM.

Thanks,
Zack

 

Wires for the rear sensor are longer.

 

Now I looked at the rockauto.com site again, and I realized that the brand AIRTEX lists a drivers and pass side O2 sensor with different part numbers? I am so confused as to which parts to order.


Thanks,
Zack

 

I got my sensors off amazon bosch universal for $40.07(only took like 20 min to assemble and posi lock seems to work good) and they work good. They also have denso oe fit for ~$55

 

But the bottom line is that both front O2 sensors are the same? Nisaan lists two different part numbers?

Thanks,
Zack
