how can i see the difference betwen oxygen sensor?

Question

I replace the oxygen sensor myself but, I don't know if I mess up with the 2 that have the same cable measure.

Answer 1

Oxygen sensor Bank 1 Sensor is the upstream 02 sensor , there is a difference between the left and right 02 sensor. Its cable lenght will measure the same but there are ear or tabs on the side that makes the difference depending on the brand that you purchase
