Variable Valve Timing Actuator code P0021
So I was driving around today and my car beeped at me with the check engine light, I took it directly to the shop my friend works at and it turns out I got the code P0021(timing issue), but they avoided giving a direct answer. My friend called me later and told me "The problem is your valve timing actuator went out, or something stopped it from working."
Has anyone else had this problem, if so what did you do and was that the problem? Thanks
