I got a check engine light that turns off and on that says camshaft position sensor A circuit range/performance bank 2. I have to drive 6hrs tomorrow and wondering if it’s something I can put off it off until after my trip or something I should fix before I leave?

The code is mostly caused by a bad cam sensor.

Since you’re going on a 6 hour trip I’d replace it.

Because when the Check Light turns on, the vehicle isn’t getting the best fuel mileage.
