Recently I got the Check engine/visit your dealer error message on the dash. Checking on my Scangauge, there were dozens of codes logged, with more coming in by the minute. I noted a bunch of them down and they all were engine (not, say, transmission) codes. A couple of them didn’t even apply to my engine (Bank B camshaft position sensor, for instance). Overnight it reset and the error message was gone.
It has now done this twice.
Given the number of codes, I’m wondering if it’s a wiring issue in the main engine harness - rodent damage, maybe?
Where is the engine CPU located?
Anyone seen this before?
