Update/Correction:
I realize I have used incorrect nomenclature. When I say TPS I mean the cylindrical sensor that is just above the Gas paddle. That is item 10 in the attached diagram which Porsche Catalog terms as "Paddle sensor". I believe the TPS is the one installed on the Throttle body...
My apologies for the error. No wonder I did not get any replies...:-)
Any help would be appreciated. Thanks.
