ok im new to the car game in the ways of electrics i understand cars have alot of weird and wounderful ways to know what its doing and can all be controlled by a magic brain as you will, allows for self tuning or emmisons as they call it, but also so the engine knows how its preforming, its oil levels hell even fuel has a sensor so as people here own fiats and lets be honest they are renound to be a little picky with these magic boxes why not make a directory of sensors on fiat cinq and sie's for people to use as reference's.

for example the

o2 sensor is loctated on the down pipes fwd of the cat on a Cinq 899cc (photo goes here)
the engine temp sensor is on the fwd l/h section of the engine fwd of the rocker cover. (photo)

and so on and so on helps people trouble shoot without constant reposting and also helps people (like me) without a handy manual to go to for reference.

sorry about all the fwd and aft i used to be in the aviation trade so its kinda the way i reference things.

Fwd = forward
Aft = After
l/h = left hand
r/h = right hand

so on and so forth u get it i hope lol

anywho i hope this thred does get updated and used would be helpful for alot of people. and im guessing rallycinq gets bored of replying to the same posts lol!
 
1. lambda sensor in the downpipe infront of the cat.
2. top dead center sensor on a bracket next to the oil filter
3. engine coolant temp sensor in the inlett manifold right hand side.
4. rad coolant sensor on the right side of the radiator controls fan.
5. throttle possition sensor on the right side of the throttle body.
6. engine overheat/temperature guage sensor on the rear of the head left side top.
7. (mk2 engine mpi) cam phase sensor right on top of the cam cover left side.
