Is the crank angle sensor a halleffect or magnetic

It appears that the CKP sensor is a Magnetic pickup that generates it's own weak AC signal. There is no V+ lead to the CKP sensor.
On the CKP connector there are 3 wires, pins 1 and 3 are White and black, and both grounds. Pin 2 blue is the sensor input to the PCM.
I'm not sure what configuration chages have to be made for the EMS to accept the CKP signal.

Inductive is the correct term, since magnetic is more generic and could refer to both Hall-effects and inductive.
BTW - what's the purpose of the CKP sensor? We've got 2 TDC sensors, can't the ECM figure out where the crank is by that? (yes, I tried a search, but "CKP Sensor" returns 5 million posts, and "CKP" is too short for the search engine).

I'm using a 00-04 ETM. (electrical troubleshooting manual) The wiring colors for the CKP are the same for all years.
The wire colors I listed are on the Sensor side, The black pin 3 changes color to brn/yel.
The CKP sensor (also listed sometimes as CKPP) Is used for timing the injectors, and as the RPM signal. It it also used to detect misfires, by monitoring for fluctuations in crank speed.
The TDC sensors are used to determine a stating point for ignition timing at start up. (the service manual also lists the are used to determine abnormal crank angle)
Hondas ETM doesn't break down how the PCM uses the supplied signals in the PCM's programming. I'd venture to say that both sensor inputs are compared to determine TDC on a specific cylinder.
Magnetic pickup and Inductive pickup are commonly used as synonyns in the Auto repair field. Modifry has it, Inductive pickup is the correct term.

thanks guys....ur all corrected
my problem is almost fixed
it was a tad difficult to start with the 1000cc injectors but I got the car fired up before coming to work this morning . It idles great too with the 1000cc. Just a little bit more fiddlings and I should be able to give the car to the tuner for a final tune up
