I checked the lights out and they were working fine, there are no loose connections, and the code only went away after I parked for about twenty minutes only to be thrown again. What could cause this to happen and what are possible fixes?
There are 2 bulbs in each brake light, so 4 total (2 on the driver's side, 2 on the passenger's side). It's possible that one of the 2 bulbs on the left brake light is dying/dead, but you just didn't notice it when you looked because the other one was still properly lit. See if that's the case, because I had the same experience.
