Not that I know of. It is a A/C voltage generator. If I remember right, it has
to put out .3V A/C
current at idle and it climbs with RPM's.
That A/C voltage goes to the Klima relay and closes a relay in it to engage the
It is a SAFETY feature:
If the compressor seizes, the compressor stops turning, the compressor speed
sensor goes to 0 volts,
relay opens, clutch disengages instantly. And you continue driving.
Loose that SAFETY feature by bypassing it:
Compressor seizes, compressor stops turning, clutch NEVER disengages, serpentine
self-destructs, engine overheats from lack of water pump flow, you loose power
steering at 70 or
whatever speed you are drivung.
Ever try steering a 126 body with no power steering???
Shouldn't be a problem until you get to slow speeds... Now braking on
the other hand.........
I am still wondering if replacing these RPM sensors requires evacuation
of the A/C system and removal of the compressor?
It would be fantastic to hear this is something that can be swapped in
with everything else intact?
