I have had both codes for a while now. It started after I was about 2 weeks late on an oil change. I have had both intake and exhaust VVT actuators and camshaft solenoids replaced . Any idea before I start sinking any more money? I'm at a loss and my mechanic wants me to take it to the dealer. I am extremely hesitant due to multiple bad dealer experiences over the last 25 years. Vehicle currently has 101,000 miles.

 

I give up. I reset the codes last evening and did some research. Had my oil changed this morning. No codes since I started it up this morning.
