2002 Toyota Sequoia oil pressure drops

Oil pressure drops off. Normal was the bottom of the 4th bar. Needle now drops down to the middle of oil gauge . Yesterday at a stop light it the neddle on the gauge bottomed out as if I had no oil pressure. The engine oil lamp did not come on so I got off the road and found it was full of oil. It now run 1 bar below normal on the oil gauge. My thought is oil sending unit or oil pump has taken a dump. Thank you, Rick

Have it tested with a mechanical gauge. If it reads ok it is likely the sender or less likely the dasg gauge itself. If the pressure is low, it could be a lot of reasons other than the oil pump…

Thank you Mustangman, Ranger
