Question about 2003 Toyota Camry
There are only a couple of reasons that this would happen: Low on oil, too much oil, or a bad sending unit. I'll cover all 3.
Check the car on level ground & don't assume you have oil just because it was recently changed. Many an engine has had the filter or the drain left just loose enough to cause oil to leak resulting in engine damage if not noticed in time. Anyway, make sure the oil is near the full mark on the dipstick. Add as necessary.
If an engine is overfull, the crankshaft will dip into the extra oil & begin to whip the oil, causing air bubbles & resulting in the inabiility of the engine to actually **** the oil into the pump. Once the car stops for a while and the oil settles, the process would happen again as long as the oil was too full. The engine will start getting noisy under these conditions. If you find out you have too much oil, you can remove the filter & drain it, which will only remove about 1/4 quart of oil each time, remember to let the engine cool first. Regardless, you must remove excess oil or suffer damage to the engine if the light is coming on as a result of that.
The sending unit can be tested by using a 12 Volt tester & hooking the clip end onto the Battery (+) side and touching the testing tip onto the oil sending unit mounted on the oil filter housing. Before testing the sending unit, disconnect it & start the car to see if the light stays on once running, if it does you have the correct sending unit to test & you just verified the connection. Now, when the oil light comes on 5 minutes after driving if the oil level was correct, test this same connection with the test light & if it comes on, you have no oil pressure or this switch is bad. Look down into the valve cover through the oil filler cap & see if there is oil being forced up to lubricate the camshaft & components you can see. If you see oil being pumped, and you aren't hearing any clicking, you do have oil pressure and probably need a new sending unit.
