Are upstream and downstream O2 sensors the same

My car has 44000 miles.
My car has an automatic transmission.

A: Hello there, the upstream and downstream ox...

Hello there, the upstream and downstream oxygen sensors for your 2013 Chevrolet Cruze are not the same. The upstream oxygen sensor is located before the catalytic converter and is used to help calculate the air fuel mixture, and is often referred to a air fuel sensor. 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. If you need assistance having this checked or repaired, a qualified pro from YourMechanic can come to your location to inspect the system and replace any O2 sensors that are faulty.
