Not exactly sure about 1999 model but It's usually located next to the oil filter with a wire coming out of it or with in the oil drain area. It's about $12 to replace.
For vehicles with an indicator light, the sending unit is like a simple switch. When the engine is off, or the pressure is too low, the switch closes, and illuminates the lamp. Under pressure, the switch is open and the lamp goes out. The only difference in the above test, is with the wire disconnected, the light is out, and with the wire grounded, the light is on.

The oil light keep flashing when i am driving but my oil was change and is full

If car drives and feels normal it could be just a bad sending unit but things need to be checked. The sending unit can be unscrewed and a gauge attached to see actual pressure if pressure is good change sending unit if it's not.... Easiest and cheapest is SEAFOAM. LUCAS also makes a good product to raise oil pressure

Go back to where you got the work done if you can.If not then i would get the oil preasure checked as the low light tells me the preasure is below 8 psi and the ticking is from the lash adjustors at the tappets verifys low preasure too.

Where is oil sending unit located

Its located next to the oil filter with a wire coming out of it. Unplug it, then replace. Here is a link a good 2001 Altima factory service manual for your vehicle if you want one for future maintenance instructions.

I have a 95 nissan altima and the oil ligth stays on for 15 seconds when its cold but then gos of, but then on stops lights it blinks.

1st I have to ask, it the oil clean and full, with a new filter? I know, it is. Just have to make sure.
2nd There is a sending unit for that vehicle that may be malfunctioning.
3rd you may have a weak oil pump. The only real test for this is to have your mechanic tap directly into the sending unit port with a manual oil pressure guage.
Obviously if the pum is bad it will need replacing which is unfortunately a costly venture.
