It looks like a little flat yellow tire.
low tire pressure
It's your low air pressure warning light, check your tires pressure.
There is no such thing as an oil pressure light on most cars. Some cars have oil pressure gauges, and all have a "Engine" light or "Check Engine" light with a picutre of either an oil can, or Engine Block The oil pressure warning light usually looks like a little red oil can. The check engine light looks like a little yellow engine.
That sounds like the "low tire pressure" light. Check all the tires for proper air pressure.
This is the tire pressure monitor warning light. Means a tire is low on air pressure or has a sensor malfunction.
