my truck spit out a check engine light so i went to go have it read.
after reading code, i started my truck again and the light doesn't come on any more.
i think the code got erased but the tech at the auto parts store said he wasn't going to clear it, so if he did it was an accident. although i not sure if computer will let you clear it unless you disconnect battery for a while or fix the problem.
i figure if it wasn't just a random mishap (since truck runs fine) it will come back on. is that a safe assumption or not?
code was (P0115) engine coolant temperature sensor if that matters any.
