Symptoms of a Bad or Failing Air Injection Hose

The engine emission system that most cars are equipped with work to reduce the amount of pollution the vehicle emits. The air injection hose is a very important part of this system. This hose helps to provide extra air to the system in an attempt to convert the exhaust fumes into CO2. The air injection hose is exposed to a lot of heat, which can wear on it after a while.

Keeping a check on the air injection hose is important and should be part of the routine inspection done to the vehicle. This hose is usually made of rubber or plastic, which can make it susceptible to damage over time. Having a bad air injection hose can create a lot of problems and will make your car release more harmful gases into the atmosphere.

1. Noticeable signs of wear or damage

Having an air injection hose with visible damage is a surefire sign that it needs to be replaced. Due to the high temperatures that this hose is exposed to, it is only a matter of time before the hose fails. If you notice abrasions or even melted spots in the hose, then it is time to see about your air injection hose replaced.

2. Idling issues

If it becomes hard to keep a car idling for an extended period of time, then it may be caused by a bad air injection hose. When the hose becomes cracked or damaged, it will let the air in the vacuum system out. This will usually create problems with idling and can only be fixed by getting the hose replaced. Not being able to have the full power of your engine while idling can create a number of different dangers when traveling.

3. Check Engine Light is on

Among the most noticeable signs that there is an issue with your air injection hose is the illumination of the Check Engine Light. The onboard diagnostic system that is hooked to the engine computer will turn the Check Engine Light on as soon as a problem is detected. The only way to get to the bottom of why a Check Engine Light is on is by taking it to a professional and getting them to pull the codes from the onboard diagnostic system in your vehicle.
