O2 SENSOR Question...........

[EXPLORINGVA]

Can anybody tell me the trick as to which O2 sensor throws off a "code 41". Is it the sensor before, or after the catyletic converter. ???
Thanks.

On a '91, you only have one (stock) O2 sensor. So a code 41 refers to the only existing sensor, the one just before the cat in the "Y"-pipe.
