M120 CMP Hall Effect Sensor
First off 1993 S600, engine only - no car.
I have been searching the internet high and low to find this information but it seems to be a great mystery somehow.
The CMP (Camshaft Position Sensor) on the Mercedes M120 is apparently a hall effect sensor, but I need to know what sort of signal generator it uses. From what I can tell without dismantling anything it runs off of the distributor's "intermediate" gear, but I don't know how. Is it a single tooth, a missing tooth, a 50/50 wheel, or something else?
Anyone ever been this far into one of these to find out?
Are they different on the later units, I know they changed the sensor slightly and perhaps (like the flex plate) they changed the tooth count as well?
Thanks in advance,
Chris
