I found this place a couple days ago and searched the codes I am getting but so far have found nothing. I have a stock 2012 ram 2500 that I bought in July of last year. The truck runs great but my check engine light comes on and off from time to time but this time it has stayed on for a while. This first started happening in September. I was driving down the road and my cil came on. I ran the codes and I got a 0606 and 0562. It stayed on a couple days and then went off until November then it came on again with the p0606 and p0562 codes along with p02E3, p0032, p2a01, p02E7. This lasted a few days then it went off. It threw the same codes around February and went off after a few days. It came on about 3 weeks ago for a couple days then went off for a day and came back on and it has been on since then. Does anyone have an idea of what it could be or what to check? Thanks

 

I'm not a mechanic, but why not stop at a parts store and most will run a scan at no cost. If I was a betting man I bet it is your .02 sensors. Same thing happened to me.

 

Don't over look bad batteries.

 

I thought about that but it has never acted slow to start. I will have a load test put on them.
