Ethanol Sensor Input Issues

Hi,
I am running the following
S300 V3
GM Ethanol Sensor - Fed with 12V, GND, and Vout heading to Analog Input 0.

I have verified connections and voltage. I have basically done everything I can without a scope.

I have chosen that input in the Flex Fuel Parameters, but I am not reading any input from the sensor when I data log.

Any ideas on what I could be doing wrong?

Thanks

Also running 2.5.0.0
installed 2.4 kOhm resistor across Vcc (12V) and Vout.

Double check the connections to the sensor and the resistor. Otherwise it sounds like it is correct.
What have you selected in the calibration? Are you running the latest software?

So after letting it sit for a day, everything works. All I did in between was reboot the laptop and ecu one more time. Go figure... I'm happy :)


I am running 2.5.0.0


Thanks
