We were trying to solve an issue with the taillight on our 2004 Toyota Camry when we saw the check engine light come on. I checked the code and it was P2118.
A little backstory: when checking the problem with the taillight, we thought maybe there was a fuse for it and it was blown, so my wife checked a bunch but no issues found. After that, the check engine light was coming on.
Would that really be triggered by a fuse, or is this coincidental? I'm a newbie when it comes to figuring out these problems...
