they "shouldn't" cause any driveability issues and i can't imagine any impending doom driving them. check engine light stuff is usually not catastrophic or dangerous. make sure it's not running hot, out of oil, and if the check engine light is flashing, that's bad. otherwise, a check engine light is not typically a sign that you're damaging an engine.
i would "guess", but not confidently, that the coolant temp sensor is more likely to cause the no start than the EGR. but i'm sort of borrowing that from older generation stuff where i've seen coolant temp sensors on the engine cause a no start condition and check engine light - i have never seen it in an EJ engine though.
i would not buy the sensors new, just get used ones. someone on here will have them, they don't fail enough or cause major issues to warrant the large expense of new. some coolant temp sensors are reasonable to buy new though, so price tha t out and see.
