Failure Symptoms

An initial symptom of a failing air control valve might be a slightly unstable idle or a minor hesitation when the throttle is applied. If the problem persists, the engine may run rougher, experience a noticeable loss of power, and trigger a check engine warning. Continued operation with a faulty valve can lead to poor fuel economy and increased emissions.

Installation Tip

Ensure the air intake passages are clean and free of debris before installing the new valve. Do not overtighten the mounting screws, as this can warp the valve body.

Service Note

When replacing the air control valve, inspect the air filter and intake hoses for any signs of damage or restriction.
