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:

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.

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.

- well here's the thing...what i think.. DanNY (91SE) 11:31:55 7/05/2002 (4)
  - It's < 5 PSI. I replaced mine with a Hobbes pressure switch for < 10 PSI. n/m The Max (92 J30 Maxima (turbo project underway)) 03:03:50 7/06/2002 (0)
  - Thanks, once I get my thoughts together I'll try the .Org n/m MIKE (93VE) 11:52:26 7/05/2002 (2)
    - The Max, info on Hobbes pressure switch, phone number, website, address, etc. Thanks, n/m MIKE (93VE) 06:26:38 7/06/2002 (1)
      - Any performance shop can sell you one of those. Also found in nitrous kits, etc. EASY to find. n/m The Max (92 J30 Maxima (turbo project underway)) 18:52:13 7/06/2002 (0)
