I have an auber 2813 and a 303 pressure sensor.
The pressure sensor has 3 wires, red black and yellow.
I have the black as ground, the red as power and yellow as the signal. As best as I could find that is correct.
But for some reason it always reads -5.5 psi at idle or even when the trucks ignition is on but is not running.
Parameters are dot2=1 pul2=-05.4 puh2=048.9 int2= 0-5v

Sorry to hear that. Your setting looks good. You can try to connect 303 sensor to channel 1 of SYL-2813, to see if any difference. Otherwise, either your sensor is bad or your gauge is bad.
