What does the code p1166 mean on the A / F sensor?
This means a malfunction is detected in the Air/Fuel (A/F) ratio sensor stemming from an incorrect voltage value registered when the power was drawn to the sensor. This code is a generic trouble code, meaning it applies to all vehicles equipped with an OBD-II system, especially vehicles made since 1996 up to present.
What happens when the Check Engine light goes on?
When the check engine light goes on, an error code is saved in the car’s computer. With the right tool, called an automotive diagnostic scanner or a code reader, you (or a mechanic) can read this code and find out what’s wrong with the vehicle.
The ECM sets DTC P1166 if no proportional fuel adaptation occurs for a defined time after the lambda controller has reached its minimum or maximum threshold. Need more information on how to fix the P1166 HYUNDAI code?

Why does my Hyundai Sonata have a p0171 code?
P0171 HYUNDAI Tech Notes If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced. What does this mean?
What happens when the O2 sensor is replaced?
If the mechanic completed the O2 sensor replacement, reset the codes and the error code was triggered again, it is possible that the catalytic converter is damaged and needs to be replaced.
Why is my Check Engine light still on after changing the sensor?
The check engine light is telling you the computer thinks something is wrong. The O2 sensor is just one out of hundreds of reasons the check engine light will come on. On some engines, the check engine light will turn itself off after the sensor is replaces, however, many require the code to be manually cleared with an ODB2 scanner.
What causes a car to have a p1166 code?

Can a check engine light be an oxygen sensor?
It seems as though the check engine light and O2 Sensor codes have always gone hand in hand. I can’t even begin to tell you how many perfectly good sensors I’ve seen replaced for a rich/lean code, or as a cure to a service engine light that comes and goes. Fact is, when oxygen sensors were first being used, they did tend to fail.
Can a check engine light code be troublesome?
Oxygen Sensors, otherwise referred to as O2 Sensors, and their related check engine light codes, can be troublesome at the very best! Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes.
If the mechanic completed the O2 sensor replacement, reset the codes and the error code was triggered again, it is possible that the catalytic converter is damaged and needs to be replaced.
