The P1682 code is a manufacturer-specific code. That means every manufacturer may have a different definition for the code. It’s very common for this code to refer to an issue with the ignition power, the engine control, or some other element of the engine control module (ECM), typically in relation to it not receiving enough power.

What Are the Symptoms of a P1682 Code?
If the problem does have to do with the engine, symptoms can vary depending on the seriousness of the problem. You’ll almost always notice a check engine light, and in some cases, you might not notice almost anything except for the light. However, on the other hand, you might also end up with a no-start condition; the engine will crank but never actually start.
What Are Some Causes of a P1682 Code?
The most common cause of this code is an issue with the ignition switch. Most commonly, you’ll notice either a failed or failing switch, with a defective switch sometimes present. If this isn’t the problem, it may be an issue with fuses or fuse boxes, issues with the powertrain control module (PCM) relays, issues with the fuel pumps, or even a problem with the PCM itself, although this problem is fairly rare.
How Serious Is the P1682 Code?
It depends on the symptoms and the actual problem. If your car is completely unable to start, then this is obviously a very serious problem–one that you’ll need an expert’s help to fix. If the car simply puts up the check engine light and nothing else, then it may not be very serious. Either way, it’s a good idea to go to an expert, as they’ll be able to figure out what’s happening in your engine and fix it.
Can I Still Drive with a P1682 Code?
This depends on whether or not your car is starting. However, even if the car is currently starting, you may not know when a problem will trigger that makes the car unable to start. If your vehicle is currently throwing this code, then it’s best to fix it as soon as possible, especially since you might not know the actual problem you’re experiencing.
How Easy Is It to Diagnose a P1682 Code?
The diagnosis process of this code can be very difficult because, as a manufacturer-specific code, the specific issues and symptoms you’re experiencing may vary from manufacturer to manufacturer and even depending on your make and model. Although an expert will have the tools and knowledge necessary to determine what’s going on and how they can fix it, most DIYers won’t. If you’re experiencing a manufacturer-specific code, especially one that so frequently has to do with the engine, then you’ll probably want to avoid trying to diagnose and repair the problem yourself.
How Difficult Is It to Inspect a P1682 Code?
The P1682 code typically has to do with small elements of the engine, which can be very frustrating to deal with by yourself. If you’re working with the engine, then it’s best to leave the problem up to an expert. That way, you’ll be more likely to actually fix the problem in a long-term context without creating any other issues. The inspection process also relies on you knowing how a healthy engine looks, and specifically the engine within your make and model, which not everyone may be able to do.
Need Additional Help with Your P1682 Code?
