This is the most up-to-date check engine code reference chart for all of Dodge including
Diesel.
2000 and newer Durango have a built-in system that can display check engine light (CEL) codes without the use of a scanner. 1999 and earlier Durangos must be read with a OBD-ll scanner. Your local auto parts store can get the codes for you either way and will usually do this for free.
hope this help let me know : - )
2000 and newer directions:
Turn the key to ON (not start), OFF, ON, OFF, ON and leave it there. If you look in the odometer window the codes will flash any code(s) with a small delay between each result. Each code should be in a P#### format, and will say PDONE when completed - turn your key to OFF and remove. Use the OBD code list to determine what problem the computer detected.
To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
Start but do not hit the throttle. Idle for about 10/15 seconds then turn off.
Restart the truck and drive as usual. It will take at least 12 starts and 48 miles to fully retune the computer. Hard Codes leave a shaddow for 40 full cold starts.
