In Reply to: sensor is a one wire deal..ground or no ground..so it'll go until it EMPTY before lighting up.. posted by DanNY on July 05, 2002 at 10:29:10:
If someone is aware they have a minor/moderate oil leak they will check their oil level more frequent, BUT if for some reason you're cruising around and all of a sudden you have a moderate to severe oil and it's day time you may driver several miles before noticing anything, that sucks. If we can have this light turn on at 20-25psi instead of 0psi I don't have to say how benificial that will be.
Ok I understand it just provides a ground, but I would think it should have a pressure rating. It's not light a fluid level sensor, like the ones that might be in a radiator and if the water drops below that sensor it will trigger a light. Since the switch is in the oil pressure flow it has to has a pressure rating. Maybe the minimum pressure rating is so low, all the oil will be gone before the light comes on just as you stated.
