In this case, it is recommended to have the vehicle inspected by a qualified mechanic to perform a thorough diagnosis. The mechanic may need to perform tests such as checking oil pressure with a gauge, inspecting the oil pump, and checking for any leaks in the system.

Another possible reason for the engine oil light to come on is a faulty oil pressure sensor.
