I like to find out. I have had engine light before now it in for replace on the Tubro 2008 Ram Meg 4x4 3500. The code I would get P2563 Tubro sensor they replace it year ago. Light comes and goes. I had a 06 with 180,000 never had a problem one. I need the 4x4, 08 had no problems till now. Plus I am in CA.
