My oil pressure gauge reads constantly low, I have a new pressure sensor ordered and will replace it in hopes of remeding the issue. On the other hand it could be the gauge, does anyone know the operating voltage of the sender to gauge? i.e. I assume as the presuure increases the voltage to the gauge does as well, can anyone confrim this. Thanks

Excellent - Exactly what I was looking for, luckily I have a resistence simulator for work so will test it out. Thanks very much!!

Odds are, it's your sensor that's faulty, and not the gauge. I just changed mine, and it reads perfectly.
