Hey guys
just wondering if anyone has had to replace this sensor before? I believe it’s an O2 sensor coming from the catalytic converter? There are two of them one on either side of the exhaust. I’ve looked at a bunch online but not sure what the differences are as some say “downstream right” or “downstream left”. One of the wires is frayed so I figured I’d just replace it. Any info would be appreciated. Thanks

Sorry for the poor picture quality
A downstream O2 sensor is just that, downstream or aft of the catalyst.
Upstream measures oxy content before the catalyst and there must be a delta reading else car will not run correctly (air/fuel, etc)

ok so when purchasing this sensor online would I order downstream left or downstream right? The sensor that is damaged is on the passenger side of the car

What’s the name of this sensor?
