A Toyota air pump, also known as a secondary air injection pump, is a component of the air intake system in Toyota vehicles. Its main function is to pump secondary air into the exhaust manifold to accelerate the activation of the catalyst during the engine warm-up process. This helps reduce emissions and improve the efficiency of the catalytic converter.
The air pump works by increasing the air velocity until it reaches a powerful force, which allows it to inject air into the exhaust manifold. It is an important part of the vehicle’s emission control system.
However, there have been reports of air pump failures in certain Toyota models, such as the Tundra. These failures can lead to issues like the check engine light coming on and the need for costly repairs. Some owners have expressed frustration with the air pump problems and the associated repair costs.
It’s worth noting that there are aftermarket bypass kits available for the secondary air injection system in Toyota vehicles. These kits can help address issues related to the air pump and provide an alternative solution.
Overall, the Toyota air pump plays a crucial role in reducing emissions and improving the performance of the vehicle’s catalytic converter. However, there have been reports of failures in certain models, which can result in costly repairs.

How much does it cost to replace an air pump?
The average cost for an Air Pump Replacement is between $492 and $597. Labor costs are estimated between $76 and $95 while parts are priced between $416 and $502. This range does not include taxes and fees, and does not factor in your unique location.
What is the function of the air pump?
An air pump is a pump for pushing air. Examples include a bicycle pump, pumps that are used to aerate an aquarium or a pond via an airstone; a gas compressor used to power a pneumatic tool, air horn or pipe organ; a bellows used to encourage a fire; a vacuum cleaner and a vacuum pump.
What happens when air pump goes bad?
The failed secondary air injection pump can cause fluctuation in power. For instance, in one minute your vehicle is performing well and in the other minute, you may face a drop in revs. Thus, you need to replace the pump to avoid continuous engine stalls and ensure a smooth drive.
How do I know if my injection pump is bad?
How to Tell If Injection Pump Is Bad
- Hard starting.
- Reduced engine power.
- Increased fuel consumption.
- Visible increase in exhaust smoke.
- Rough idling.
- Delayed response during acceleration.
- Misfiring.
What does an air pump do in a car?
The air pump pumps compressed air into the exhaust manifold and in a few cases to the catalytic converter. The oxygen in the pressurized air helps to burn quite a bit of any unburned hydrocarbons (fuel) and thereby converts the poisonous carbon monoxide into carbon dioxide.
Is an air pump important?
An air pump is not essential to all ponds however the benefits cannot be ignored. The addition will ultimately improve the health of the pond, creating a more suitable environment for all aquatic life whilst also assisting to manage the levels of waste.
What does Toyota air injection pump do?
In Toyota trucks, to accelerate the activation of catalyst when warming up the engine, the air injection system pumps the secondary air to the exhaust manifold by pressure.
Do all cars have an air pump?
Not all cars have air compressors built-in. Some vehicles may have a small air compressor for inflating tires, but it is not a standard feature in all cars. Some car owners may choose to carry a portable air compressor for this purpose instead.
How much does it cost to replace air injection pump?
The average cost for an Air Pump Replacement is between $492 and $597. Labor costs are estimated between $76 and $95 while parts are priced between $416 and $502. This range does not include taxes and fees, and does not factor in your unique location.
How can you tell if you have a bad air pump?
The most obvious sign of a broken air pump is a lack of air flow or pressure. If the pump is not producing any air at all, then it is likely that the pump is broken and needs to be repaired or replaced.
