P2330 is a diagnostic trouble code (DTC) for "Ignition Coil K Primary Control Circuit Low". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $114.99 . Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.0 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
When the PCM of a vehicle logs a P2330 trouble code, it’s because there is a problem with a primary or secondary circuit and the way its interacting with an ignition coil – in this case, ignition coil K.
Almost every modern automobile uses a “coil on plug” system to create the spark required for bringing an engine to life. In fact, it’s probably fair to say that any vehicle advanced enough to have a PCM (Powertrain Control Module) also has a coil on plug system working for it.
There are usually over 30 coils per vehicle which is why there are 35 trouble codes related to their operation. A lot of times, if you find P2330 has been logged, you’ll notice a number of others related to these coils have too. Whatever the case, this code means something is wrong with ignition coil K’s circuitry.
You can find these ignition coils on the top of a vehicle’s ignition plug. They’re powered by electricity controlled by the PCM. This electricity is also how these coils create the igniting spark we mentioned earlier. However, before that happens, a voltage signal must be received by the PCM from an ignition coil.
Each vehicle has an acceptable range of voltage for this job. If the voltage that the PCM receives from ignition coil K is too low, then P2330 will be recorded.
Sometimes, this trouble code is marked down in the system despite the fact that nothing is actually wrong. In that case, it’s the PCM that is responsible. That’s pretty rare, though.
More often than not, it will be one of the following:
If ignition coil K quits working properly, the check engine light should come on. Other symptoms a driver may experience would be:
To diagnose the problem, a mechanic will need to:
A very common mistake when addressing this trouble code is simply applying a tune-up to take care of the problem. That’s not to say this is a bad idea simply for the sake of maintenance, but it’s rarely the solution in and of itself.
Until the underlying problems are addressed, you will most likely have a very difficult time operating your vehicle. Though it may not be dangerous necessarily, drivability will be affected which is never something to take lightly.
Replacing or repairing any of the following may be necessary to clear this code:
In some cases, it may even be necessary to replace or rebuild the entire engine.
Sometimes, wildlife is the cause behind an ignition coil becoming damaged and, thus, triggering a P2330 code or a related one. If that’s the case, you’ll want to be careful about where you park, especially during the winter. Those of you who live in a cold climate may have a car that attracts wildlife because it’s so warm under the hood shortly after it’s been driven.
