Sir, you need to add the year of your Dodge Truck so the members can help you.

I too would like some help. Been trying to fix my dads 07.5 6.7 that is doing the same thing. Installed new apps. I did read that the sensor is sensitive to sufficient power supplying it, so we are getting batteries load tested tonight.

Check your battery cables, especially the ground cables.
