what is the throttle positioning sensor in the fiat punto. and what does it look like. because i have a problem with flatspot. and need this info to help me. thanks this would be very much apreciated.

sorry if this is in the wrong section.

Re: tps

its inside the throttle body located to one side of the butterfly - there is a cable going to it making it easier to locate (other side will have the throttle cable on.) AFAIK it isn't removable and so faults with the TPS require a new throttle body.

Re: tps

the throttle position sensor is just a variable resistor, when you push the accelerator pedal the TPS will change its resistance (moving along a carbon film track changes resistance as throttle position changes) which will adjust the voltage signal that returns to the ecu from the TPS. the ecu uses this information when determining fueling and ignition.

i've never come across a flat spot that was caused by a TPS fault, however fitting a scrapyard throttle body is the easiest and cheapest way to test your theory.

Re: tps

Im sure a mod will move this

throttle potnsiometer is replaceable

it just pulls out and new one pushes in

there is a fiat tool for the job but it easy enough to bray out with a hammer and screw driver

as for flat spots i would be looking to the map sensor and pipe work or lambda sensor
