No . No problems & this code hasn't come back. I really just didn't understand what the code meant. Ie, something is about to go bad/ out. Such as the ECM, etc,. Truck sat for about a week while I was on vacation. Went to start it & engine light came on. I cleared it & not had any problems. Just wanted to solve a problem ( if I have 1) b-4 it goes out on the road
