What Is An Air Diverter Valve?

Operated by the air bypass solenoid, the air diverter valve works almost the same way a pump check valve would. Both parts keep exhaust in the system but allow air to be pumped in, opening to allow air to enter and closing to prevent exhaust from escaping.

These valves help to control emissions using a variant of an air pump, and whether belt-driven or electrically activated, they inject air to allow the same fuel to reignite or reduce exhaust escape.

Common Signs And Symptoms That You Need to Replace An Air Diverter Valve

• Subpar engine performance
• Car is unable to pass emissions tests
• Large amount of fumes escape from vehicle when driving (an abnormally significant amount)
• Check Engine Light is lit

How Important Is This Service?

Often times if there is an issue with the air diverter valve, the check engine light will automatically turn on. However, if it fails to do so but you face any of the other symptoms, especially failing emissions tests, have this checked out immediately.

Having the faulty valve replaced will not only improve your car’s performance and save you on mileage and increased emissions fees if applicable, but you will also be commended by environmentalists and animals alike for helping reduce our massive carbon footprint. Hey, you have to drive but now you’re doing it cleaner.
