Can't find the o2 sensor behind the catalytic converter
The mileage for our 1993 sl2 has dropped drastically. We replaced the o2 sensor in front of the catalytic converter but the mileage is still "going south". We want to change the "behind sensor, but can't find it. Can you help?

Is your check engine light on? If not, then your sensor is more than likely fine. Here's one picture I found to show where the secondary sensor is. It also shows the socket tool in the picture.
I believe vagman54 is right. I overlooked the 1993 part. I think the secondary sensor is an OBDII (1996 and newer) thing.
If its a 1993 there wont be one behind the cat
