If the check engine light stays on despite good oil pressure and the engine running well, it could indicate a variety of issues such as a faulty sensor, an emissions system problem, or a minor engine issue that needs attention. It's essential to use an OBD-II scanner to read the error codes, which can provide specific insights into what may be causing the light to illuminate. Ignoring the light could lead to more significant problems down the line, so it's advisable to have the vehicle checked by a mechanic.
