Code P1166 on a Kia Optima typically indicates a problem with the fuel level sensor or the fuel gauge system. This code suggests that the engine control module (ECM) has detected an issue with the signal from the fuel level sensor, which may result in inaccurate fuel readings. It's advisable to check the wiring, connectors, and the sensor itself for faults to resolve the issue. If necessary, a professional diagnostic can help pinpoint the exact cause.

Error code P1166 is a primary indicator that the ECU/ECM is receiving negative feedback from an O2 sensor or a bad O2 sensor control. Running a Oscilloscope is actually not a bad idea in this case, and if it proves to be an O2 sensor, it is most likely the one behind the catalyst control. The only other thing that comes to mind that may trigger a P1166 is a leaky air intake system, and that can be solved by doing a simple smoke test before you end up taking the sonata to Hyundai. I would definitely recommend doing this first. If it turns out to be a leaking intake, then that will save you a lot of time and money. The reaction that your car is having at this time is typical for a faulty air system or O2 sensory as well.
