Subject:      Need O2 sensor shield help / advise

I recently replaced my 02 with the generic sensor
from Bus Depot. When I stripped the wire, I did not
notice a braided shield. If there was one, I would have
missed it because I made a clean cut right to the center
insulation. The center wire had what looked like a teflon casing.

Should I tear it apart, and look for the shield ?
How do I know if the 02 sensor is working properly?
If the only way is to measure voltage, I have a cheezy
$10 Radio Shack volt meter, do I need something more accurate?

Electron diagnosis challenged am I!
