What is the Air Pump Check Valve all about?

In a secondary air injection system, air must be injected into the exhaust system, but exhaust fumes must not be able to escape. This is accomplished by using a one-way air pump check valve. Think of it as a one-way street -- air can enter, but exhaust gases can't leave.

These secondary injection systems are used to ensure a fuller burn of spent exhaust gases, which both improves fuel economy and eliminates pollution from the vehicle exhaust. It’s an important part of your emissions system. Generally, the air pump check valve is mounted near the top passenger side of the engine, although this can vary. Some vehicles have more than one check valve, as well.

Over time, the air pump check valve is subject to not only high heat, but also other forms of damage. It can deteriorate and degrade. While there is no set lifespan for these components, they can and do fail.

Keep in mind:

  • The air pump check valve is not inspected during normal maintenance.
  • A failed valve will cause the Check Engine light to turn on.
  • Your car cannot pass an emissions test with a bad check valve.

How it's done:

  • The air pump check valve is verified to see if it needs to be replaced
  • The defective air pump check valve is removed
  • The new air pump check valve is installed
  • The air pump check valve is tested for operation
  • The vehicle is tested to ensure proper operation of the air pump check valve

Our recommendation:

A secondary air injection system is an important part of your emissions control, and the air pump check valve is a critical component. If it fails, it’s possible for exhaust gases to escape, or for fresh air to be blocked from entering the exhaust system. If you suspect a problem with your air pump check valve, have it diagnosed and repaired by one of our expert mechanics.

What common symptoms indicate you may need to replace the Air Pump Check Valve?

  • Check Engine light on with check valve failure code
  • Will not pass emissions test

How important is this service?

While you won’t notice much in the way of performance degradation if the check valve fails, your Check Engine light could come on, and your car will not pass emissions testing. Because of this, you should replace a faulty air pump check valve as soon as possible.

GMC Jimmy V6-4.3L - Car starts and then dies - Louisville, Kentucky
Overall I had a good experience with Brandon as My Mechanic. I used this service to diagnose a problem with my 2000 GMC Jimmy in which Brandon ended up diagnosing the problem as a bad fuel pump. Unfortunately, replacing a fuel pump isn't a repair he offered on site which was one major downside and flaw with this service. I think Your Mechanic has a great idea to have the mechanic come to you and is why I went this route to begin with, but when your repair isn't offered on site it really defeats the whole purpose because if your car isn't running you can't drive it to where they need it and i was using this service to avoid tow fees to begin with, and on top of that when you can't have the repair done you lose the perk of using your diagnosis fee towards the repair, so I was really disappointed in that aspect. Brandon was an affable, punctual, and most of all knowledgeable mechanic whom I would recommend to others if what is wrong with your vehicle is an on site fix. He even gave me a way to contact him personally in case his diagnosis was wrong. I have yet to have the repair done, but I am confident that the fuel pump is and was the problem with my truck. Another plus was that he explained to me how he came to that conclusion by telling me his thought process along with showing me the supporting evidence of each step. He also looked over my engine to inform me of some other minor problems with my truck.
