Am I missing something (oh-two sensor)

[shivas irons]

I've got an 1996 T&C LX. I just replaced the Oh-two sensor on the exhaust. However, when I go to do the ignition test I am still getting a code 21. Is there something else that I need to do to reset the computer or is there something else that I need to do with respect to the sensor. This sensor, btw, had to be stripped together as the clip was not available.
Thanks in advance,
RR

You need to clear the code in the computer. Remove the battery cable, Positive, and wait about 5 minutes before reinstalling it. That should reset the computer and remove the code.
