Code P1682 Dodge Description
The P1682 diagnostic trouble code (DTC) for Dodge vehicles indicates that the charging system voltage is too low. This means that the voltage output from the vehicle's alternator is below the expected range, which can lead to various issues with the electrical systems in the vehicle. The alternator is responsible for charging the battery and providing power to the electrical components while the engine is running. If the voltage output is too low, it can result in a lack of power to crucial systems, such as the ignition, lights, and other electrical components. This can lead to poor vehicle performance, stalling, or even the inability to start the vehicle.
Common Causes of P1682 Dodge
- Faulty alternator that is not producing enough voltage.
- Loose or corroded battery connections, affecting the charging system's ability to function properly.
- A damaged or worn-out drive belt that is not effectively transferring power from the engine to the alternator.
- Faulty voltage regulator that is not regulating the voltage output from the alternator.
- Electrical system issues, such as a short circuit or a parasitic draw, draining the battery and causing low voltage output.
Symptoms of P1682 Dodge
- Dimming or flickering lights on the dashboard or exterior of the vehicle.
- Difficulty starting the vehicle or frequent stalling.
- Loss of power to electrical components such as the radio, air conditioning, or power windows.
- Warning lights on the dashboard, such as the battery or check engine light, may illuminate.
How to Fix P1682 Dodge
- Start by checking the battery connections for corrosion or looseness and clean or tighten them as needed.
- Test the alternator's voltage output using a multimeter to determine if it is functioning properly.
- Inspect the drive belt for any signs of wear or damage and replace if necessary.
- Check the voltage regulator for proper operation and replace if faulty.
- If other electrical issues are suspected, perform a thorough inspection of the vehicle's electrical system to identify and repair any faults.
Cost to Fix P1682 Dodge
The cost of repairing a charging system voltage too low issue can vary depending on the specific cause of the problem. In general, the cost of replacing an alternator can range from $300 to $600, including parts and labor. If the issue is related to the battery connections or drive belt, the cost may be lower. It's important to consider diagnostic time and labor rates, which can vary based on the location and type of repair shop. It's recommended to get a detailed quote from a trusted mechanic before proceeding with the repairs.

I have a 1998 dodge durango 5.2l and I'm pulling a p1682 code. Any clue what this is?
-
We have updated the information. Looks like you may have a problem with the alternator. Before checking the alternator, make sure the battery is fully charged.
-
Thank you. I had the battery and alternator tested and it came back there fine
-
Do you have any driveability problems? if you don't then, you could try just erasing the code for now. According to the service manual, there is nothing else. If the battery and alternator are OK, then the problem is the PCM
-
It is drivable. I erased the code and it came right back on. No check engine light. Could it be the cable or bad connection?
-
Yes. The problem is that the PCM is not getting the correct voltage (between 12.9 and 15.0), since you know that the alternator and battery are OK, then you should check the wires from the alternator to the PCM. Check the "Generator Fiel Connection" wires on the alternator.

Just put a remote start in my 2000 3.9 V6 RWD and am now getting p1682. Sometimes she'll start with remote start, sometimes it will just kill the battery. check gauge, airbag, voltage low all pop up at once. Related to remote start? Where to look. Mechanic says needs new altinator. It's not two years old. No problems before remote start
-
If the problem started after installing the remote start, then it's very likely that the problem is with the installation. You should double check the remote starter installation or contact the remote starter manufacturer to see if there have been any more incidents similar to what you have.

i have a 2001 dodge ram V8 5.9L that i just bought the PCM, Alternator, Brand new Battery and now got this code. This all because of a NO BUS on my odometer. Now i get this and P1687 code also. Where do i start??? and a code of 137 as well.....HEEELP
-
With the engine running, check the voltage at the battery. What voltage do you get?
