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.

BMW 750iL V12-5.0L - Serpentine/Drive Belt - Plano, Texas
I highly recommend Adam to anyone needing work to their car or truck. I own 2 old BMW 750iL 12 cylinder sedans. I'm talking 25 and 28 years old. They both have been in storage for about 6 years. One of them had a broken fan belt which I called Mobile Mechanic to send some one to replace it. The person they sent was Adam. Adam was on time for our appointment. He called the day before to introduce himself and disgusted with me the work to be done. Upon his arrival the day of our appointment, he was very polite when he introduced himself to me. He then went to examine my car and what needed to be done in my presents. After his examination he informed me that my water pump may had seized up and it was what was causing the belt to break. He suggested there also may be other things wrong such as the fan clutch that is attached to the water pump may also be froze up. He suggested that I not put the belt on but take it to a garage for further examination. We agree to this and he left without charging me anything. What an honest guy. I did take his advise and the next day had the car at the garage and they found that Adam was right. Both fan clutch and water pump froze up and that is what caused the belt to break. Adam not only saved me the cost of replacing another fan belt which would have broken if he replaced it but also the possibility of getting stuck on the road when the new belt would have broken because of the other 2 problems. Adam was honest enough to inform me of the possible additional problems even at the cost of him not getting the original job he was sent to do. When I get the other car out of storage it is my intent to call Adam to check it out and let me know what needs to be done.
