If the “Check Engine” light illuminates on your 2000 Dodge Durango, you can isolate the engine trouble codes at home without incurring the cost of an expensive diagnostic test at a dealership. The trouble codes will identify the source of the problem, helping you narrow your troubleshooting efforts to correct the problem. If you do not have a source to decode the numeric key, a local auto parts retailer can provide the definition for any code that appears.
Sit in the driver seat of your Durango. Insert the key into the ignition.
Turn the key to the “ON” position, then quickly turn it off. Repeat the process. Turn the key to “ON” and leave it.
Watch the odometer display area for engine codes. The codes will flash, and will be four-digit numbers preceded by a “P.” Each individual code will flash, and then “PDONE” will appear after the last code.
Turn the ignition key to the “OFF” position. Remove the key from the ignition.
Raise the hood of your Durango. Disconnect the negative cable from the battery using a wrench.
Insert the key into the ignition, turn the key to the "START" position, leaving it for 15 to 20 seconds. Turn the key to the "OFF" position and remove it from the ignition.
Connect the negative battery cable, tightening the connection with a wrench. Close the hood of your Durango.
