Dodge Nitro: Engine Problems / Code Errors

When retrieving Dodge check engine light codes with an OBD II scan tool, proceed as follows:
1. Connect scan tool to the 16-pin data link connector (DLC) located near the steering column. The connector may have a removable cover.
2. Turn the ignition on.
3. Follow scan tool manufacturer's operating instructions to access the Diagnostic Trouble Codes (DTC's).

Remember, these are manufacturer specific codes only. Refer to our Generic OBD II code list for definitions on all other Dodge diagnostic trouble codes.
