Crank and cam sensor Circuit voltage

[Jordan1083]

Car- 95 eclipse GS (non turbo)
i have another Thread devoted to this issue but its so large I get lost in it http://www.dsmtuners.com/forums/420a-bolt-tech/337591-no-spark-starting-think-ecu-since-its-95-a.html#post153184091


What I know: both cam and crank position sensors are Hall effect sensors that put out voltage from .03 to 5-8 volts on the sensor output pin.

What I dont know: what is the voltage on the output wire when the ignition system is in run and the engine is NOT running.

Currently getting 5v on both sensor wires Pin 25 and 26. THis power is coming from the ECU. Is this right or is the ECU bad. I want to confirm this before I blow money on ANOTHER ECU.

request- Someone with a running 2g NT eclipse check voltage on Pin 25 and 26 of the ECU with the ignition switch in the run position and engine NOT running then post results.

Thankyou for anyone who takes the time to help me out.

The voltage on those wires depends on where the crankshaft and exhaust camshaft were when the engine was last shut off. It will either be low (~0V) or high (~5-8V). I suppose something in between, like 3V, would indicate a problem.

The voltage you measure when the car is running isn't very useful. Since the signal is a complex square wave, a multimeter will average it, and different multimeters will average the signal differently.
