Oil gage light is going on and oil was just changed

My Lesabre has buttons on the left side of the dash. The one called Gage Info has a number of things like oil pressure check tire pressure heat Battery. Push this button till it says check tire pressure To reset your light push the reset button and hold for fifteen or twenty second and the light on the dash should go out and it will show tire pressure ok on the gage. Before you reset check all four tires for air as one tire could be down 8 or 10 lbs and the light will come back on. they all have to be the same pressure.
When you change your oil you should reset the oil section as well and hold reset the same as above. The oil section tells you how much oil you use over an amount of time.

Check your oil level and antifreeze level or change your oil if the problem continues

did you change the oil and filter? if the gasket leaked oil into the cooling system or coolant into the oil it.ll mess things up look at the oil, milky white? got water look at the coolant got oil? flush radiator and replace coolant i hope you did'nt put the head gasket in upside down

chances are the oil pressure sending unit is not working or unplugged it is located by the oil filter. the low level oil sensor is in the oil pan and is not related to the gauge .make sure to tell the parts person weather oil sending unit is for a gauge or a light

Replace your oil pressure sender and see if the dash warning lights turn off. If after changing the oil pressure sender you still have oil pressure warning lights on, you may have to replace your oil pump in your oil pan.

That is the oil pressure gauge not the oil level gauge. Sometimes they can act that way when the oil is thin. When is the last time the oil was changed? Try using a heavier weight oil. When engines wear they require thicker oil. What size engine does you voyager have?

Have either autozone or auto discount...depending on your location, they will check it for free an tell you what the problem is.. they can reset it..however it will continue to come on until the problem is resovled

At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana

Yoyu dont mention the mileage on your Yukon but low oil pressure will indeed light the CES light when it reachs o psi. Have you checked your oil? Have you changed your oil and filter. High mileage and poorly maintained motors will eventually wear out and develope low oil pressure. A tempary cure would be to use a higher weight oil 20w50 will get a few more miles out of the old gal if indeed the cam, main or rod bearings have reached their service limit.. Good luck

change the oil sending unit.
