My 2011 Honda CR-V has 82,000 miles on it. The check engine light came on six months ago. As the weather warmed up the light turned off and the car passed the emissions test during annual inspection.

Below Threshold Bank 1

I bought the CR-V new, fifteen years ago this coming May. In Massachusetts, a 15-year-old car is exempt from emissions tests. What to do… what to do…
