timing gasket failure - oil pressure sensor

Since our G's have a stupid not really working oil pressure sensor, I was thinking what I could do without having to install a separate oil pressure gauge etc.

Does anyone know how the current sensor works exactly? From reading here it appears the sensor/ ECU doesn't really trip anything until oil pressure is around 5 psi or technically too late for either the time gasket failure or other engine problems.

Was thinking if one could possibly fool the ECU some what and install a different oil pressure sensor that would get you a low oil light below 14 psi. I am assuming that the car's computer doesn't really know what the oil pressure really is but that the sensor at some point in time when the pressure is really,really low triggers the light.

Maybe there is a Nissan or other brand sensor that could be used.

anyone have any idea if this would work.

I had mine installed off the pressure sensor on the oil filter housing, I see 14-15 all the time, WR set for 10 PSI
and I have over 100k miles( KNOCK HARD on wood) LOL

I am trying to avoid installing a new/additional pressure sensor gauge.

Was hoping I could fool the car/ecu or whatever and throw a low pressure light at 10-13 psi vs the 5 psi.


The question is, does the current OEM sensor actually measure the pressure and then sends the info to the ECU, and the ECU decides to only trigger the light when the pressure is at 5 psi. Or the pressure sensor doesn't actually measure the pressure and only detects something when the pressure is really really low like 5 psi then tells the ECU to trigger the light.

The stock sensor is only a switch, it can't measure pressure like you want.
Cheers.

makes sense.. so if one could find a switch that goes off at 10-13 psi that would do the trick.

The only issue I can see is, the factory would have deemed the pressure switch was set at a point that would not give annoying false alerts.
Such as when pulling up to a stop with a hot engine (thin oil slightly less pressure) may sometimes trigger the warning light if set at a higher pressure.
Honestly I think a gauge is the best bet if you are concerned about this issue.

You can keep it pretty stealth, I have some of the PLX DM6 Gauges mounted between the A pillar & the dash. You can set warnings, max/min etc.
