2or4strokes Posted April 15, 2009 Share Posted April 15, 2009 Hi fellow guzzi enthusiasts I remember reading about a harley TPS which can be used for the california 1100i. Can someone please provide me the part number, year and model of bike for this particular PFC4 tps from harley because my harley dealer knows nothing about a PFC 4. The original PFC 3 from guzzi is ridiculous priced at 230 euro. thanks Link to comment Share on other sites More sharing options...
fotoguzzi Posted April 15, 2009 Share Posted April 15, 2009 the harley TPS is interchangeable with the EV 1100 from '98-'01.. your cal 1100i uses a larger housing and different TPS that is not changable to HD.. unless you modify the holder.. if you find a cheap substitute please let me know.. My friend w/a cal 1100 has problems we can't fix and we suspect the TPS. price is too high right now to experiment w/a new one. Link to comment Share on other sites More sharing options...

I remember using it on my sports 1100i 1997 model and reading about this as a replacement for the PFC 3 sensor used on the sports 1100i and california. Anyway my california is also 1997 year. Can some other enlightened soul help me out on this? Link to comment Share on other sites More sharing options...
gstallons Posted April 15, 2009 Share Posted April 15, 2009 Do you own and can you use a DVOM? if you answer yes to both you can test the tps. It is a potentiometer with 3 terminals. Supply v , V ref (signal return) and gnd. Two teminals wil read the same resistance at all times with the other changing resistance with the wiper movement. You are going to watch for erratic (fluctuation) readings with the wiper movement. Link to comment Share on other sites More sharing options...

I know nothing about the Cali but hopefully you can boil the following down to something useful: From what I've gathered for future use, the Sporti (and V11) uses a PF3C and has been replaced with a PF4C by numerous people with good results, although it's not identical in characteristics. Harleys part no for the latter is 27271-95. I also have some notes about Centauro/Daytona, they use a PF09 TPS. In case your Cali has that one, substitutes are said (@COG forum) to be "Weber WTP024. Ford cars - Sierra and Escort Cosworth 4x4 wheel drive versions - and the Alfa Romeo 33ie. It was also fitted to the Ducati 907i and possibly other early to mid '90s Ducatis" gstallons is right too of course. I suspect that lots of perfectly fine sensors are replaced without need. On the other hand, a borderline TPS could be hard to diagnose. Think of how the volume knob on your grandma's radio could produce devastating noise at first when you turned it, but after you excercised it, it was fine for a while. That was precisely the same type of component - a potentiometer. And that one didn't even have to put up with heat, cold, salt and moisture.

fotoguzzi Posted April 16, 2009 Share Posted April 16, 2009 my experience w/the friends cal 1100i (I think '96) the TPS is much larger physically.. the EV and my V11 Lemans use the same TPS. I have tried the HD sub and can't notice any difference from a good stock one, accept the price 42.00 from chicagoharley.com I know someone else w/a 97 cal and he made a new holder so he could adapt the HD TPS to the older throttle body. but I don't have a pic of it.

Today I saw a california vintage year 2006 using the same tps as my v11 copa italia and also my sports 1100i. My california also uses the same PF3C which I took out and put onto my sports 1100i because it is faulty. How do I know it is faulty? My mechanic has the diagnostic eqpt. and the reading from the TPS fluctuates and cannot be held constant even when tighten. I swapped it with the working one and this problem disappears. Thanks for the part no. RAZ. Will be calling Harley tomorrow. Link to comment Share on other sites More sharing options...
