Air Injection System Air Bypass Valve Replacement

How are Air Injection System Air Bypass Valve issues diagnosed?

This component is diagnosed differently depending on the form of actuation. Vacuum actuated valves will be tested by pulling vacuum on the solenoid and watching the valve for opening. For computer controlled systems, a digital scanner or outside power source can be used to open the valve on demand. If the valve fails to open or close in either case, it will require replacement. Of course, that is after confirming associated electrical circuits are functioning properly.

How are Air Injection System Air Bypass Valves replaced?

Replacing the bypass valve will differ from vehicle to vehicle, but generally speaking the valve should be simple to remove from the air pump or hose, and there should only be one electrical connector to remove. Many times, the use of tools may not be necessary. Installation is also straight forward, and the only concern is assuring the valve and hose is sealed from air leaks.

RepairPal Recommendations for Air Injection System Air Bypass Valve issues

Since the air injection system uses rubber press-fit hoses and other components subject to deterioration, any time the system is serviced it is advised to perform a complete inspection of the secondary air system. This includes inspecting for exhaust leaks where the air injection system connects to the exhaust manifold or exhaust pipe.

What to look out for when dealing with Air Injection System Air Bypass Valve issues

Portions of this system become extremely hot to the touch as they are directly connected the the exhaust system. Any time this system is service, ensure that the engine has had adequate time to cool. Laser thermometers are advised to locate high temperature areas prior to servicing the system.

Can I replace the Air Injection System Air Bypass Valve myself?

Anyone can replace the air bypass valve, and the failure may be obvious due to leaks in an air line or a disconnected hose. However, if the fault is not obvious, diagnosis should be thoroughly understood and performed correctly in order to ensure the valve is not replaced erroneously.
