Hi, I have a 95 240sx.

When I measured the voltage going from the rear O2 to pin 52 of the ECU, white wire, O2 signal, I got 9.8volt-I know that's way off, it should have been between 0-0.7volt, right?

When I measure the voltage going to pin 108 of the ECU, blac/white wire, I got 12.3volt-It's that correct? What should be the voltage going to pin 108? Thanks
