Got home and found out that the interior's of the sensor were different. After thorough inspection and a little reading, found out resistances are the same for all the TPS's, just design difference. So I went and picked up a newer TB to go with my sensor (as I couldn't find an older sensor), calibrated it and installed it on my engine, and *VOILA* TPS CEL goes away.

Its as simple as that??? Wow, thats great!!! I''ll copy this message so that I'll know what to do when I encounter such problems..
