Question about 2007 Dodge Ram Truck
Seems that my mileage is rapidly going down down down. It seems that that that check eng. light came on after I changed the batt. and oil. Now I'm getting a red lighting bolt sign light on dash as well. what's going on???
In both cases, there is a software update available for this condition. It involves
having the dealer connector their StarScan tool to your truck and
reprogramming the PCM.
DTC P0406 - EGR Sensor "A" circuit "High"
There is updated software available for your PCM that will correct this code if your vehicle was built prior to mid February 07. If it was built after that, then the EGR valve will need replacing (this is not unusual). Keep in mind that could be time for a new valve, but you dont will need to change the tube, but new gaskets are a good idea.
DTC P0524 - Oil Pressure Too Low Oil pressure sending unit (sensor) voltage input above the maximum acceptaple voltage.
If the software is up to date, then have the oil pressure sensing unit must be replaced.

I know your probably a little apprehensive, but stop at a dealer and have them check it. It's EGR related and should fall under emissions warranty if your within the perimeters, as well as there is mention of a computer update related to that.
