Hi
I have a VDO oil pressure sensor connected only to AdcVcc1. I calibrated sensor using excel sheet on tutorials topic.
Utcomp shows bit low readings compared to resistance value measured with multimeter, that can be fixed changing calibration values. But what I have not solved is pressure values changing with battery voltage.
Example: utcomp showing voltage 14,2V and oil pressure 1,4bar Then I switch on heated seats and driving lights, voltage drops to 13,6V and oil pressure goes to 0,1bar, engine RPM stays the same in both cases.
Sensor model and values
