What's one of them do then?

No sensors on mine! Cable goes from your foot to the manifold. that's it!

Motronic cars (post 1987) have AFM (air flow meter) instead of a throttle position sensor....Measures the volume of air flowing into the engine rather than using the position of the throttle plate to say how wide the throttle is open...

AFM is more accuarate

erm, does the M10 not have an AFM, I think it does, and I don't think it has a TPS..
