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.

Chris was prompt and professional. He provided a detailed description of the work completed and possible areas of maintenance I should be considering for my vehicle based on his inspection. I would not hesitate to contact him again for any service I might need for my vehicles in the future. It was a great experience.

Hello, I have a 2000 Toyota echo that works all handy dandy. However I have an issue with the car. Every time I get gas, the car has a really hard timing turning on. It takes about 3-4 cranks to get the car started. Once the car gets started, it doesn’t have an issue turning on. I do have a check [engine](/topics-engine-toyota/) light on and the codes are p0440, p0441, and p0446. I know these are common codes with the car and I did my research. So far I have replaced the purge solenoid under the hood, I replaced the charcoal canister underneath the car, and I just got the lines flushed for carbon build up. I did take it to a mechanic but he said he couldn’t find anything else wrong with it. I find that hard to believe and ima get my money’s worth from this guy later. My only and last thought on the issue could be the pressure in the engine or the flow of air. I know the pressure is too lean in the car and that could be the main reason why it’s having a hard time turning on. They mechanic did mention something about the PSI being at 45 which is too low. How can I fix all of this?

How can we help?
