I took my 2.0 Turbo Hyundai [Sonata](/topics-sonata/) to the dealer for diagnostic. They came up with a P0299 code. I replaced inter cooler today as suggested and Turbo still not kicking in, picking up speed. What should I look at next? Mechanic's Assistant: Just to clarify, what's the exact code?

I just replaced the intercooler
