Default is250/350c convertible top issue

Hey all, I know there is a thread dedicated to top issues, but it appears to be inactive (I posted a question and havent gotten a response), so I thought maybe if I asked in a new thread someone mght see it and have an answer! Also, I read all of the posts/responses in the other thread and there doesnt seem to be an answer to this specific question....

I have an is350c and am having issues with the top. I scanned it, and if memory serves me it is a position sensor in the right hand package tray/trunk hinge that is the issue. I will rescan and verify. My question is this: can the sensor itself be replaced, or do I need to replace the whole mechanism just to replace the sensor? Thanks in advance for any help!

Default Same boat…

Same boat but LH package tray, 2010 IS350C. Had this one a bit over two years without issue. Have a B254C code now (Side Package Tray Switch L). Had a B265C (Lock in Side Package Tray Motor LH Circuit) a month ago that went away after re-lubricating the tracks.

What codes do you have? Maybe we can compare notes? Hopefully someone will give us some tips.

I have found this site to give some diagnostic procedures as well.
