Question about 1993 Saturn SL2
Thanks vagman 54 and jeffk14. Now the parts place is saying there are 2 sensor in the engine compartment. one of which is located near the firewall. I just don't don't know if that's true of they don't want to refund my money for the part. Can you help?
The sensor is in the exhaust pipe just ahead/in front of the catalytic converter. the other sensor is the catalytic converter efficiency monitor, looks like an O2, but has a different function, this is behind the cat in the exhaust

Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2
Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2
Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.
Sensor 1 is always the upstream sensor (the one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.
Hope helps (remember to rate this).
