GrahamU 6 Posted October 5, 2014 I want to run a fuel pressure sensor on my car and have the pressure displayed on a digital readout. I've seen they have them on diesels and the tfsi engines so thinking of using one of those, So assuming I get one of these and the signal output is 0-5v I will need to calibrate it by confirming its output at various pressures. I dont easily have access to any setup that can put a known pressure using liquids but I can do it using air pressure, would using air pressure on it be the same as putting a liquid pressure?
