Maserati - Alfa throttle pots

[Almichie]

This was totally accidental. I was watching a movie this evening drinking some lovely badger beer (hoping hare) and thought "I wonder if the Alfa GTV had a pedal pot like the 3200" And it turns out they do. So I'll be doing a little more digging and may well buy a few variations to try. They're all the Bosch type and should bolt right in and as long as the fed back is the same it may well be another part that could save a few £££.

I'll keep you updated as I learn more.

Be careful. there are many cars with Bosch pedal pots, but none to my knowledge, with the exact output of the 3200. i think it was a special and that's why it was so expensive. It must have two outputs both the same, and 0.35 to 3.5 volts out and they both need to be within 0.015v of each other (matched) its generally the difference between these two that causes the errors, that and wear and poor grounding. They also have stiffer springs than standard pedal sensors because the idle voltage has to be within i think around 0.02v of where it was calibrated. Maserati clearly regretted the stupid spec around these sensors as they were changed for the 4200, both the sensor and the limits at the ECU. but if you find one excellent!!!

That is correct.
I have to say that measurements at the pedalpot of a 2005 Alfa 166 3.0, showed exactly the same values as the pot of mij Gransport, both output 2 = 2 x output 1.
But i am not completely sure it fits, as i did not check if they both turned the same way, CW/CCW

By the way; the Alfa pedalpot is not very cheap, i think it is also around 450,- euro's.
By the time i get troubles, i will convert the pedalpot for the Gransport to contactless, as i did for the Alfa.
They are a solid problem at the Alfa's as well, bringing the automatic gearbox to insanity if they start failing.
