Want to check the crank angle sensor on my y reg 2001 MPI fiat seicento 1108cc - check my previous posts as to why I want to do that. Where is it - there is something on the top of the timing belt cover is this is it? also if anyone has a service manual for this id appreciate one very much im [email protected]

Cheers

The bulge in the cam cover is a cam sensor.

Crank sensor sits on a bracket on timing side of engine by the crank.

PM me re. the factory Sei manual.

its okay ive checked the sensor and it does work

So what does the cam sensor do then? - caught a glimpse of it when I did my rocket gasket, and did wonder what the hell it was...

The truth is, no-one seems to know, or no-one is telling.

Earlier MPI's, like the Punto 75, don't have the cam sensor.

I thought that the later MPIs had sequential injection, Oldschool says it doesn't. Maybe it has semi sequential injection?

God only knows. :bang:

I always assumed it was sequential as well...

What I don't understand is that it doesn't seem to sit low enough to take a reading from anything anyway - and the engine ran as well with or without it (which I've noticed on a friends schuey as well).

Not too bothered about it really - just thought I'd ask to see if it served any obvious purpose... guess its a bit like the appendix then

My early MPI seemed to do sequential or semi-sequential injection at lower rpm but at higher rpm was batch fire. My latter MPI didn't seem to do any kind of sequential injection. I'm fairly sure the two cars used different ECUs which may explain things I duno.
