Hello and thank you for your question,

When the light came on did you hear any unusual engine noise?

Customer: replied 1 year ago.
No, no noises and did not notice any difference in how the car was performing.
Expert:  Ron replied 1 year ago.

In most cases it the engine was not making any rattling noise due to low oil pressure and seems to run fine you are most likely dealing with a failing oil pressure sensor and not a bad oil pump. That being said, I would start with removing the oil pressure sensor and installing a Manuel gauge to verify you have proper oil pressure and if that checks okay then replace the oil pressure sensor.
