A P0320 code indicates an issue with the signal that indicates the speed of the engine. This means that the ECM (engine control module) doesn’t know where the crankshaft or camshaft is, so it isn’t able to distribute fuel or fire spark plugs at the right time. This can be a significant problem, and if it loses track of the engine signal entirely, your car may not even be able to start.

More About the P0320 Code
A car is an incredibly well-tuned piece of machinery, and it needs to know how to move each piece in conjunction with other pieces for best results. The P0320 code shows that the ECM has stopped being able to tell where the crankshaft and camshaft are in space. The crankshaft is a piece at the bottom of the car motor, allowing it to convert the vertical movement of the pistons into rotational movement; the camshaft does a similar thing but nearly in the opposite direction, converting rotational movement into vertical movement. Both of these need to work perfectly to make sure your car starts and runs appropriately.

What Are the Symptoms of a P0320 Code?
Depending on the actual problem you’re experiencing, there are a number of different symptoms that you might experience regarding a P0320 code. The check engine light is the most obvious and should come up regardless of any other symptoms. You may also notice issues with the power to your car, the engine stalling or misfiring, and even the engine cranking to start but not actually starting. In some cases, however, you can also notice nothing except the check engine light.
What Are Some Causes of a P0320 Code?
Technically, the code itself doesn’t give you any insight into where the problem is, only that there’s an issue with the speed of the ignition or distributor. That means there may be a problem with the speed sensor for the engine, the position sensor on the camshaft, or the position sensor on the crankshaft. However, the problem can also be due to an issue with the crankshaft’s reluctor ring or simply because the battery is weak and isn’t communicating properly with the sensors.
How Serious Is the P0320 Code?
This all depends on the actual problem. If the problem is that the battery is simply faulty and you’re not experiencing any other serious concerns, then it may not be very serious at all, and you’ll just need to replace the battery. However, if the problem is that the sensors are misfiring and the engine is starting to stall regularly, it can be incredibly serious. If your engine is throwing a P0320 code, then it’s best to talk to an expert to diagnose the problem.
Can I Still Drive with a P0320 Code?
Technically, you may be able to drive with a P0320 code, but not always. In many cases, a P0320 code will actively inhibit your ability to drive the car, which can mean that you need to get a tow truck or a home visit to fix the problem. However, even if you’re physically able to drive the car, it’s still best to talk to a professional about your options for fixing the problem permanently. Ignoring the problem makes you more likely to experience engine damage.
How Easy Is It to Diagnose a P0320 Code?
The diagnosis process for a P0320 code can be much more difficult than it seems because it typically requires you to check a variety of elements within your engine. Additionally, most modern vehicles have a spark voltage of 10-15 kilovolts, which can result in a lethal shock. This is a much more advanced diagnosis process that’s not generally recommended for beginners or car repair hobbyists, especially because putting the vehicle back together again is just as important and just as difficult as taking everything apart.
How Difficult Is It to Inspect a P0320 Code?
The inspection process can also be very difficult. You’ll need to do a lot of work to check wiring, power, ground connections, and issues with dirt, as well as wear and tear. Instead of trying to do the inspection part of the process yourself, it can be a much better idea to talk to an expert and have them determine what’s really wrong.
Need Additional Help with Your P0320 Code?
Because the P0320 code has to do with your engine, it’s best not to take any chances with it. If you do, then you might end up with a worsening problem that requires you to pay significantly more to fix the problem. Instead, it’s a better idea to take your engine directly to an expert who can help you fix the issue early on.
The best way to do this is to use Kelley to find repair shops near you. This makes it easier for you to get your car in and fix the problem before it develops into something worse.
