A little insight into the TPS, there is no hard and fast rule with them failing like most electronic parts. They are are variable resistors and work using a wiper rotating across a carbon track and from continuous use can wear the carbon track or the wiper weakens and does not make with the track correctly. I have come across a smalll number where water has seaped in through hairline cracks This setup is used in many items most common ones are a volume control in a Radio, the fuel sender in the petrol tank of many cars and bikes or the remote control in some game consoles.
The TPS is sealed on bikes for obvious reasons
See pics, which are courtesy of engineers garage as I dumped the old ones I had since they are rarely repairable.They show how they operate and the make up
The usual reason the fuel tank ones fail is from wear on the lever mount which can be fixed.
There are spurious one available, but unless they are a reputable brand eg.Tourtec keep away from them.
Some honda Transalp 700 fuel sendeers fail and are part of the fuel pump which is over €700. Some of these can be repaired also as it is from float lever wear.
Just be glad you don't own an Alpha Romeo as like many cars have a TPS and are are part of the Throttle body. When they fail you have to buy the full throttle body. The Alfa ones are a very common failure with a throttle body costing 1000s. There used to a fellow in the UK who did repair them but not sure if he still is around.
