TPS failures - better designs - Digital Encoders!

[KasaRyan at aol.com]

The way to go if one wants something that is not affected by the environment 
like a Pot is to use a Digital encoder.  A one turn encoder is available in a 
hardened industrial form by any of several controls suppliers.  PLC direct, 
allen-bradley, toshiba, etc.  The problem as stated earlier is cost - but if 
you have a digital line in then it is the way to go. - It would be very 
possible if one wanted to run the digital output to a DAC and run that to an 
ECM.  Or just be careful not to spray the TPS with the hose when engine 
cleaning.
