Aux Canister Kia Recall

The Auxiliary Canister on a Kia

An auxiliary canister is a component of the evaporative emission control system (EVAP) on a Kia vehicle. It provides additional benefits to the main canister. For example, it protects the canister from contamination during refueling.

The EVAP has several components, including the main canister, the auxiliary canister, and the hoses, valves and electronics that are needed to operate the canister. While the primary canister has the most important function of all, the auxiliary canister is a good complement to the primary canister in a number of ways. When installed correctly, the auxiliary canister may improve the performance of the evaporative emission control system. However, there are some potential problems with it.

The auxiliary canister is a small, charcoal canister that acts as a secondary filter to collect fuel vapors. As a result, it improves fuel economy and reduces emissions. If the canister is not functioning properly, fuel vapors may be released into the air and can cause a hazard. Gasoline vapors are dangerous to inhale and can lead to headaches, nausea and more. A faulty canister can also result in a strong smell of fuel escaping from the vehicle.

In some cases, a failing canister can even result in a fire. While this is not an immediate danger, it does present a risk of more serious harm. That’s why you should have your evaporative system checked on a regular basis. Even if your evaporative system seems to be working, it is still recommended that you have your canister tested regularly.

One of the auxiliary canister’s most prominent features is the heater. The heater is a preferably electrically conducting ceramic. Electric power is provided to the heater via the auxiliary canister’s electrical connector. Unlike the electrically powered engine fan, the heater does not require a constant supply of electricity during normal operation.

The auxiliary canister also has a first flow passage and a second flow passage. These features help to maximize gas absorption. The auxiliary canister’s first flow passage connects to the corresponding vent port on the auxiliary canister. It also communicates with the sorbent material in the auxiliary canister.

The second flow passage communicates with the sorbent material in another compartment of the auxiliary canister. This is an interesting feature that should be considered when evaluating the auxiliary canister’s design. Moreover, the auxiliary canister’s second flow passage also serves as a means of cleaning out the sorbent material in the auxiliary.

There are numerous possible problems with the auxiliary canister, and you should have yours inspected on a regular basis. Having your evaporative emissions system properly tested is the best way to ensure that your vehicle is in compliance with emissions regulations. Also, having your canister inspected is an inexpensive way to ensure that it functions safely and efficiently. With that in mind, don’t try to fix the auxiliary canister on your own. Contact your dealer for advice.

Whether you have a Kia or another brand, you should take the time to check your auxiliary canister. A failed EVAP test can lead to several issues, from poor fuel mileage to an on-board diagnostic trouble code.
