Just took the girl out for a run. I stopped after about 25min of driving. Got back in and started her up and check engine light came on.
Drove for another 25min before I got home. Did the key dance and got codes 53 (ND cal) and 43. I thought I got a 56, too but after looking at the chart it's possible it was a 55.
Car is running great, no issues. Any idea what would cause the code 43?
