You probably have a stuffed oil pump or possibly a crook oil pressure sender. when it comes to oil pressure always start of by thinking the worst stop driving until you KNOW what the problem is.
This is the check tire pressure light. you either have a low tire or bad sensors. Toyota sensors have a problem where if the tires are under 35psi the light eventually comes on, even if their recommended pressure is 30. The spares on the suvs may also have a sensor.

If the light comes on there is a code. Have the code checked and fix the cause. If the light is on with no codes, then you have a computer problem.
Not continuous; comes and goes.
Intermittent
Have the charging system checked. The light comes on when there is a charging system problem. it may be a battery, alternator or a battery problem.
Depends on which light you are referring to. The "Check Engine" light comes on when there is a problem with the emissions system. The "Maintenance Required Light" comes on when scheduled maintenance is required as outlined in your owners manual.
Oil pressure is low- check fluid level, if ok may have restriction somewhere or possible pump problem.
If you problem is that the gauge shows oil pressure with the engine off, you have a gauge or sending unit failure.
you can disconnect the negative cable at the battery for at least 30 seconds. if the problem is intermittent, the light will be out afterwards. if it comes right back on, seek a shop that does engine diag.
Low oil pressure is typically caused by worn main and/or rod bearings. If the oil level is up the problem is almost always the bearings. Rod and main crankshaft bearings ride on a thin film of pressurized oil. Once the bearings wear out the gap between the crankshaft and the bearing increases, allowing the pressurized oil to leak out. The pump cannot produce enough volume to keep the pressure up, then the pressure drops and the sensor turns on, indicating that you have a problem. Try switching to a heavier grade oil. That will be thicker oil which does not leak out as fast. Pick an oil with higher viscosity numbers to see if you can get the oil pressure to go a little higher.
Lucky for you, the 2001 Toyota Corolla comes with a timing chain and is good for the life of the engine. No need to change it.
