I took advice of japanese friend owners, open the TPS to inspect and do some cleaning up. My TPS condition is actually pretty good, a bit carbon dirt but all other metal pins and resistance board are all good, pictures for your reference. If you want to do it , just cut through the edge of the top "cover", you will feel it if you have cut through the glue, it took me 2 hours. Then use a small screw driver to pop the cover up, you will see the resistance board, cut the glue on the top and bottom edge and it can be pop up.

Extremely interesting as these are hard t come by these discontinued, no? If I have a spare, I might have to give this a go.

 

Thinking: lets say you do get into this, how best to clean it? The DeLorean had these terrible rear light circuit boards that always corroded and we used to use a pencil eraser to clean them up. I'd have to imagine there is a better method then that these days! ha.

I think it's discontinued, and probably no more new part available. Japanese mini owners do have some options to get a modified TPS and I think if you are a good DIYer you can modify yourself, just get an aftermarket sensor and make an adapter to install. The mini factory sensor is turning clockwise if you look at the manifold side, see picture.

I have seen an adapter sold in Japan that lets you use a later/easier obtained TPS. At least there are options out there.

Electrical contact cleaner spray or methylated spirits on an cotton earbud to remove the loose worn material.

 

Based on current experience worn TPS is becoming a bigger issue as spiking voltage input confuses the MEMS ECU and few NOS parts left.

Yes but I guess it makes it easier for any future replacements...
