Don's conclusion:
The construction of this potentiometer is obviously not suitable for the application. Considering that in the life of the car there will be multiple millions of cycles of the throttle, the action of the hard metallic finger tips riding on the soft thick film carbon resistor element is a designed-in shortcoming that will result in an estimated 100% or more, failure rate in the life of the Volvo automobile.I am glad that I drive a throttle-by-cable car!

Ah, a wear-through failure of conductive ink. I'm shocked.
Co-Molded conductive plastic Pots,
such as those made by JDK of California last for millions of rotations and resist "dither" far better than cheap film pots.
Problem is, they cost significantly more. A few bucks never seems to bother Lexus does it?
does this affect deisel cars 2002
