2007 Ram 4.7 Flexfuel 136,000 miles.When Key is turned to the ON position CEL light illuminates solid for 5or 6 seconds and then goes off and then starts flashing.It is not on while driving though.Ive never noticed this before.Anyone know what that means?

 

its probably the cel sensor. my 08 does the same thing but for the tire pressure sensor

 

does it blink then turn solid when key is in the acc/on position after the 6 seconds? or continues blinking? this relates to your i/m readiness status

 

its in the manual anyhow
