The temperature gauge, you know the thing that keeps track of the temperature so you don't overheat it, only works when it feels like it and even then it only works for 5 or so minutes. It's annoying it has caused me to overheat it on multiple occasions due to another problem I've been having with it. I've replaced the temp sender or something and it did nothing to alleviate either problem. CEL code was for the coolant sensor circuit high so I bet it's wiring or something.
