Zetec Throttle Position Sensor (TPS) Spring Loaded?
Tatey - 19/5/12 at 09:52 PM

Evening all,

I am currently trying to devise a way of mounting a TPS to my ZX6R carbs (I bought them without realising a needed a TPS for megajolt), and I've heard of someone making a pulley system by using the throttle return cable to rotate another pulley which the TPS is mounted to, and I was wondering if the zetec TPS is spring loaded so it will return to the 0 position when tension isnt being applied by the cable?

Or if not is there an easier way that I don't know about? The throttle spindle is pretty small on the carbs and I'm a bit dubious about drilling into it.

The zetec TPS is sprung and returns to 0 when released. No reason it cant be mounted on the pedal or the Throttle spindle but you could even make up a housing at some convenient point on the cable with a nipple operating a short arm which is attached to a spindle and this could operate the TPS.

I used the mondeo one on a set of Twin 40's I managed to get it mounted to the throttle spindle I used polymorph to help me to attach the two. Polymorph is a mouldable plastic

Thanks for this Dusty, I think I will use this design however change from the single hole for the nipple to a slot, as the way the design is at the minute ,as the arm rotates it will follow an arc and increase the tension on the cable, and could potentially jam the throttle if theres enough tension/friction to overcome the return spring of the TPS/throttle, whereas a slot should allow the cable to move freely.

I managed to pick up a TPS from Gaz08 on the forum today so hopefully soon I'll have my TPS mounted.
