Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electric Air Control/Electric Air Switching Valve
The electric air control/electric air switching valve (EAC/EAS) combines both diverter function and the air switching function into one integral valve.
In addition to normal diverter valve function, this valve can be electronically controlled to provide divert air under any driving mode.
The second section of the valve can be electronically controlled to provide the air switching function. This is to provide direction for air not diverted to the air cleaner.
