Customer reply replied 6 months ago
It is OK on oil as per the dip stick and is making no unusual noise
Toyota Mechanic: tims auto repair, mechanic replied 6 months ago

ok..

here is what you need to do..

you need to remove the oil pressure sender and install a mechanical test pressure gauge to check the pressure..if the pressure is good,replace the sender,if the pressure is in fact low..the oil pick-up strainer in the pan may be clogged or the oil pump may need to be replaced
