| RE: new fault code 1664 where to start ? basically it looks at the temperature drop between the doc intake and the dpf intake. If it doesn't see a big enough difference in temperature during a regen then it assumes that the doc is either missing or damaged. I would check sensor readings first during a regen and go from there. | |||
