Default small turbo phase sensor voltage.

Bosch phase sensor originally mounted on escos eec-iv. How many volts does this need?
12v or 8v? This is a hall sensor so i guess 8v volts,.. but you newer know before you know you know

Searched forum and 12v is stated, but anyone running these on 8v?

Originally this would have most likely been a 5 volt reference feed, 5V is fairly typical for ecu's sensors.
So long as powered and working it will produce the square waveform needed.

Do you mean the camshaft positioning sensor? If so, this has a 12v feed.

The sensor doesn't "need" any particular amount of current, it is the disturbance of the electric field as the trigger passes it, this change is what acts as a on/off square wave signal, so long as it has whatever the ecu puts out, and the engine is turning over fast enough it will work.
