P1166 HYUNDAI -

Question

Auto Zone checked & stated the code was \\'PL1166\\'. Could not tell me what the code meant. I have a 02 Hyundai Sante Fe w\\65,000 miles. The check engine light does not stay on and the car seems to runs good, could this be for a scheduled maintenance? Thank you

You could start by changing the engine oil and checking for intake leaks.
