So heres my story. I changed my oil one day and only put 5 quarts in (knowing I need 5.5) and after a little while the low oil light came on. I checked the oil, it was a little low, but I thought it had to be more than 2 quarts low for it to come on. Anyway I filled it up and the light was still on. I tried reseting, came right back on. After about 3 oil changes I finally changed the low oil sensor when I did my last oil change. I disconnected the battery for a hour. I started it up and the light was gone....for about 5 minutes. It's on yet again and I have NO clue why. The oil level is fine and the sensor is brand new and connected. Any ideas what else I should check to make this thing turn off? Is there a certain way to reset it besides just disconnecting the battery?

 

Maybe i'm wrong, but doesn't that light come on with low oil pressure also?

 

Not sure, but there is plenty of oil pressure.

 

doesn't that light also come on when its due for a change? Also for the record, disconnecting the battery doesn't clear OBDII PCM's of any codes.

Try the proper procedure in resetting the oil life indicator.

 

I'm fairly certain that there's a specific "Change Oil" light on my '02 Z28, and that doesn't stay constantly lit, just for the first bit of having the car on then it goes out until the next start.

I don't see what resetting the oil life indicator would do for a low oil light, unless the 99's are different

But I could be wrong

Maybe the sensor has gone bad or the wire broke?

 

OK you guys are on the wrong light Its the LOW oil light not the CHANGE oil light that is on. The change oil light comes on when you are supposed to change the oil and its reset by using the little button on the odometer. The LOW oil light is the one that is triggered from a sensor in your oil pan. The CHANGE oil light just appears after a certain number of miles.

 

THat's what I was trying to say, and saying that if you have enough oil and enough pressure then maybe the reason why it's reading low is because your sending unit is on its way out, or a wire or connection is broken loose or corroded

I'm sure I said something about not seeing what resetting the oil life indicator would have to do with a low oil light

 

I have a 98... no oil life indicator, just a low oil light... also no black box heh.

Maybe the wire is broken or grounded out...

 

hey i have a 96 lt1 and have the same prob. Not low on oil at all and the light comes on

 

Did you put in a thicker viscosity oil? i had my old 3.4L throw that light b/c i put in 15w40

 

98's did not have the oil life monitor. 99-02 have them.

 

and even then its a computer calculation, no actual oil life sensor like the vettes.

 

Nope used 5w30 fully synthetic like always.

And just to make sure everyone is clear its the LOW oil light, not the oil life indicater aka change oil light. Huge difference.

 

ok guys it is telling him the car is low on oil not change the oil! did you change the oil sending unit.?

 

Did you check your fuses and relays? Any blown? A bad ground? Check all the wire for the sensor and follow it and see if you can see where it goes/if its corroded/broken/burnt on exhaust manifold/header, clean the connector with electrical contact cleaner too. Also try resetting the oil life monitor, see if it works, can't hurt.
