From your inicial post you mentioned that the secondary sensor or cat monitoring sensor is the one that is giving the code. If your cat is damaged or removed the light should come on because the secondary sensor (CMS) has detected that the cat is not operating. When the post cat oxygen sensor mimics the pre-cat sensor in regards to signal output it indicates that the cat is not functioning.

P0142 is for bank 1 sensor 3 02 malfunction, which the s2k does not have.
Sounds like someone ran the wrong protocol.
Get the thing scanned correctly, then post the code.
Your last decription does not coincide with the code.

Ok, so it must have been p0141 bank 2 (Sorry guys I was just going off of memory which is NOT good at times). So if its the heater circuit, is that basically telling me the cat is FUBAR'd and not the sensor thats tripping the CEL?

this post is old as dirt but me and airgate had our cats fail and it killed both our 02 sensors. same weekend (mcdragon).
He went with high flow cat and i went with a used 30k mile cat (thanks dougEfresh).
we both went with the Bosch universal and we are both stuck with the p0141 code. Has anyone used the Bosch and had it work?
i have several hundred miles on it and have had the cel cleared several times only to have it come right back on.
if i put a good one in, how do i get this cel to turn off and stay of assuming the O2 sensor is working properly ?
$60 vs $250 i had to give it a try. its not as if Bosch is a fly by night start up. why would this not work?
