Hi, My 2008 Hyundai Sonata has code# P0011. What does that mean?

Question

Answer 1

Hi there,

It's a bit complicated. The car has variable timing. This code means the timing is over advanced. This is usually caused by the oil control valve that is used to adjust the timing. This can also be caused by low oil level as well. I would first check the oil and if it's full the next step will have to be to have the ocv tested for performance.
