* Manufacturer-specific: Chrysler (who made the Sebring Convertible) might use this code internally for their diagnostic system. You'll need a Chrysler-specific diagnostic tool or software to understand its meaning.
* A misreading or error: The code might have been read incorrectly by your scanner, or there's a problem with the scanner itself. Try a different scanner if possible.
* An extremely rare or undocumented code: While unlikely, it's possible this is a very obscure code not widely documented.
To find the meaning of P1684 for your Sebring Convertible, you should:
1. Consult a Chrysler service manual: These manuals often contain detailed diagnostic trouble code information specific to the vehicle's year and model. You can often find these online (some are free, others are paid).
2. Use a Chrysler-specific diagnostic tool: Generic OBD-II scanners often won't interpret manufacturer-specific codes. A professional-grade scan tool designed for Chrysler vehicles is more likely to give you a proper definition.
3. Take it to a mechanic: A qualified mechanic with access to diagnostic equipment will be able to read and interpret the code, and diagnose the underlying problem. This is often the most efficient and reliable method.
Without more information (year of the Sebring Convertible), a precise answer isn't possible. The year significantly affects the vehicle's computer system and diagnostic codes.
