Why do I lose air when I Disconnect my suspension pump?
The air you hear when disconnecting the pump is actually air from the pump’s hose. When you put a pump back on you lose some air pressure in the air can due to it charging the pump again. That’s why recording (i.e. writing down) your setup is important for riders looking to tune their suspension to suit their individual wants and needs.
How to replace a secondary air injection pump?
Step 1: Locate the air injection pump. The air pump is at the front of the engine with the serpentine belt wrapped around it. Tip: Make sure there is a belt routing diagram under the hood of your car so you know how to reinstall the belt. If not, take a picture of the belt routing with your phone before proceeding further.
What happens when the air pump fails on a car?
When it fails, the overall performance of the engine may suffer due to the lack of air. Many states also have strict emissions regulations for their road going vehicles, and any problems with the air pump or the air injection system can not only cause performance problems, but also cause the vehicle to fail an emissions test.
What are the components of an air injection pump?
The air injection system introduces oxygen into the exhaust engine at certain times to reduce emissions. Typical system components include the PCM, air injection relay, air injection hoses, valves and the pump. The air injection pump can be either belt driven or electric – for this article, we will focus on the belt-driven design.

What happens when a secondary air injection pump wears down?
A secondary air injection pump that is wearing down can cause inconsistent power gaps from the engine. One minute the power may be fine, and the next it may be weak. If the pump is not replaced, the power will stay weak.
What are the symptoms of a failing secondary air pump?
When the check engine light is illuminated, the ECU runs in a ‘limp home’ or safe mode which may cause the following symptoms: Other less typical symptoms you may experience with a failing secondary air pump may include: Erratic vehicle power after initial start-up.
Is there an option to remove the air pump?
This option leaves all mechanical and electronic components within the engine compartment, maintaining the original engine appearance. This option removed the most obvious air pump components from the engine bay, providing a cleaner appearance and reducing the difficulty and time required to change the LH spark plugs.
