Question:
Hello, after a LOT of looking, I found a site that explained how to test the three sensors in the distributor housing. (CYP, CPS/CKP, & TDC).

The specifications require that the resistance of each sensor should be 350-700 ohms. Each one of my sensors reads exactly 341 ohms. Given this consistency, I blame my cheap ohm-meter, but if the sensors also test low on a better meter, would they need replaced?

Would 9 ohms under spec cause any problems? Would this be a sign that my sensors are slowly "wearing out" or something?


Procedure: for anyone else who wants to do this. (At least on a 2000GSR)

1)Pull the plug that is attached to the distributor housing.
2)There will be spaces for 8 small pins (with only 7 spaces having pins), and there will also be two big pins (can ignore)... the small pins look like this:
1 2 3 4
/ 6 7 8
3) Each vertical pair of pins are the connectors to one of the three sensors.
a) Pins 2-6 are for the crankshaft position sensor (CKP/CPS).
b) Pins 3-7 are for the TDC sensor.
c) Pins 4-8 are for the CYP sensor.
4) Using an ohm meter, test each pair of pins, they should all have between 350-700 ohms.
5) Test each small pin (1-8) individually for continuity to a chassis ground... if there is continuity, there is a problem. (exe: one lead to pin, one lead to a ground)
