i had my cam sensor replaced two weeks ago. aparently they shop left the coolant fill cap off. i now have a check engine light. can this be why and how can i fix it?

the coolant being low probably did not turn on the light,unless it was really low and the car overheated. im gonna assume that this is a 4 cylinder car since you said its a base model. most of the time ive seen a cam sensor code it turns out to need a crank sensor instead sso it might have the very same code stored in it as before.

Doubtful leaving the cap off tripped a check engine light. That could be due to any one or more of literally hundreds of things. You need to get a code reader on the car, Autozone will do it for free, that will give you an idea of what the problem could be. It may be as simple as a loose gas cap.

Took it back to shop that did work. They checked it and determined was faulty part. Hopefully new one won't be.

my car temprature is hi can i fix it
