Check engine light on “fuel pressure sensor” have replaced. It is still on???

What is your question?

I have a 2006 Dodge Ram 2500 4x4 5.9 liter diesel. Started when changed the fuel filter w/k&n filter. Pressure sensor error. Replaced fuel filter with oem. Light went off, then came back on. Took it to the dealership they replaced the fuel rail sensor. The light came back on before I got home. Took it back to the dealership. He told me to drive it “hard”. So I did. After a couple days the light went off. Then the light came back on after 4 days of driving. Tried driving it hard again. Light is still on. Any ideas? Check engine light came on when sitting idle.

How long has your 2006 Dodge Ram 2500 had this problem?

Couple weeks
