First off i was driving to work a day or two ago and the oil light came on, so i shut it off checked the oil and sure enough it was low, so i filled it up with some more, i checked it again and is a little over the correct level but its ok.

My question is i keep checking the oil and it's a little high but doesn't drop, but the oil light is still on,

Can it be b/c i filled it a little high, or would it be say pressure, sensor, or leak somewhere?

now i can run codes because i have an aem ems, and i have an oil pressure gauge but not hooked up, so it seems like im stuck in the water,

BTW i am trying to figure this out so i can drive it again it hasn't moved much since the light went on

any help is greatly appreciated!

 

If the light dosn't extinguish I would check the oil pressure sensor, there's probably a guide in your helms manual to checking resistance across the sensor.

With most sensors they act on some kind of variable resistance which gives a read-out to whatever component decides it's within a good or bad zone.

With an ECT sensor it has a negative temperature coefficient which causes resistance to drop as temperature goes up, which in turn moves your temperature gauge up and down depending on coolent temperature.

My guess with oil pressure is it measures resistance depending on pressure applied to the sensor, the higher the pressure, the lower the resistance between 2 pieces of metal.

Like I said though, look in the helms manual for troubleshooting faulty sensors.

 

ok, that makes sense i have never come across this problem before, and wanted to ask before i just go checking things out,

ill check the manual later today thanks

you're running an AEM EMS and your oil light is on? is the stock pressure sending unit hooked up? if not hook it back up. if it is, install the oil pressure gauge and make sure you have oil pressure before running the car any more.

 

yeah i thought that was wierd too, but the stock pressure sending unit i believe was never taken out or unhooked but ill double check that, if it is, how am i supposed to hook the gauge up, through the stock pressure sending unit or maybe a sandwich plate? its a mechanical autometer gauge, and i have the autometer isolator, just at home and im in school,

any suggestions?

 

sandwich plate or a T off of the stock sending unit. I have a T on mine.

I'd guess either your stock sending unit came unhooked or your oil pump took a crap. Probably the sending unit.

 

well, i just checked the sending unit and sure enough it was hooked up, so where can i find a t-fitting for it so i can hook up the pressure gauge? anyone know im in southcentral minnesota......

 

The honda stock oil presure sending unit has 1/8 inch BPST threads.
there was another post about his some time ago but I don't know where the guy found an adapter.
FWIW that sending unit is a switch to ground to turn on the light, just continuity test from the connector to ground to see if it is staying grounded.

 

thanks for all the help, im gonna try all this tomorrow!

 

i just found out the jack is broken, so i have no way of really working on my car, i checked the oil levels cold compared to operating temp and heres what i came up with-

cold- normal level
warm- a good inch above high level

does that mean anything? anybody else?
