I am looking for the TPS output voltage lead wire. Does anybody have a diagram or info it looks like there's four wires going to the TPS and throttle body thanks

This is for S-type MY2003, 4.2 litre. NA, but I think, that it is the same for X350.

 

Awesome I will verify the part numbers are the same thanks so much

 

Original TPS (S-type) is DENSO 198500-3300. It is not possible to buy independently. On e-bay are OEM parts, described as "OEM 198500-3300".

Original DENSO have output from TPS from 0.82V to 4.26V, OEM from 0.82V to 4.32V. All right, it is in the border.
BUT (OEM part, which I bought) :
Original DENSO have output from IDLE from 1.56V to 4.35V, OEM have output 0 everytime.
I don´t know, if IDLE output is significant (I think yes), but with OEM TPS (after calibrating to low value to 0.82V), engine won´t start.

 

Actually all I need to know is which wire is for the TPS voltage output to hook to my Nitrous system.

 

Yes it looks like all 02 to 08 all have the same sensor. Your part number matches mine! Now I know its wire 3 assuming its from looking at it from the front which would be red...Thanks so much Roman!!!
