P0456 code and more

I have a P0456 code that justcame up.Three of them and one of which was permanent, So I can’t clear the codes. Meanwhile my cruise control no longer works and I’m about ready to scream. Under 3k miles on the TRD pro and this. I search through the forum for answers and I could not find any. I have an appointment with Toyota on Tuesday but I just wanted to see what you guys would say. Thanks

 

It’s an easy fix, which they will.

Is your gas cap on all the way?

300 miles? Sounds like a you should take a trip to the dealer.

 

3,000.
Truck is worn out.

 

Make sure your gas cap is on correctly. My old 4Runner would throw a similar code if I forgot about the gas cap

 

Yeah I checked my gas cap. It’s just weird that the cruise control just stopped also.

 

Were you getting the CEL light with intermittent TracOff light? If you checked your gas cap, see if the code reader can clear the codes now.
