Frequently Asked Questions (FAQs)

1. Are GM O2 sensors interchangeable?

The downstream sensor is a heated oxygen sensor and reads the emissions after the catalytic converter. They both function the same but are different enough that they cannot be swapped.

2. Are aftermarket oxygen sensors any good?

It's true that you may find an aftermarket oxygen sensor that's advertised as better than OEM. There's still no guarantee that it'll outperform an OEM oxygen sensor when it comes to working with your ECU and withstanding the continuous exposure to hot exhaust.

3. What is the difference between bank 1 and bank 2 on O2 sensor?

Brian, the questions I am asked most often about O2 sensors is how do you know what is Bank 1 or Bank 2, which O2 sensor is Sensor 1 or Sensor 2. Bank One is always the bank where cylinder number one is located. On the Corvette it will always be the driver side. Bank Two is the passenger side.
