Analog input problem

[joseedgardosanchez]

Hi every one, my problem is that i connect in the s300 v3 white board on analog 0 input my nitrous pressure transducer. The problem is that i no see any voltage on the analog 0 input with the ecu connected on it. Them i disconnect the wires and connect one voltage step down from my 12vdc to 5vdc to my analog 0 input to make the troubleshooting and i no see voltage on the sensor window and display windows see 0 voltage. i read the voltage with digital multimeter and read the 5 voltage (for test purpose). I will appreciate your attention

What conversion are you using for the analog input?
