In a 1998 Felicia 1.3 MPi. Would it be fair to assume that if the speedo is
working properly then this sensor is working properly? If not is there any
way for the average bod with a multimeter to test it?

the speedo sensor is completely different to the crank sensor.

either can be tested for continuity and if you spin the engine or the wheel
you should get a faint voltage pulse out of it (think under a volt AC), best
way is substitution though.

So I've discovered from Briskoda. Jorily Skoda, who sells bits on Ebay,
threw me by describing the crank sensor as a speed/speedo sensor; I've since
been told that the speedo is cable driven anyway.

Ta. I don't think there's anything wrong with it really, but I'm looking for
idling problem solutions. I have a couple of things to try yet before
hair-pulling.

"Mungo \"Two Sheds\" Toadfoot" <eastREM...@gmail.com> gurgled happily,
sounding much like they were saying:

It really doesn't take that much thought or mechanical nous to realise
that there's no way that a crank sensor _can_ measure the road speed.

Definitely not. Unless you want a revcounter rather than speedo.

Presumably you've cleaned & readapted the throttle body?

Hmmm... well now that you mention it... :-)

Cleaned, yes. Readapted - tomorrow.

Yes, yes, I wasn't thinking it through, ok? You see "speedo sensor" and a
picture of a crank sensor together...
