Electric Air Control Valve for Toyota SUVs and Trucks 🔧

This component keeps your engine idle stable by metering bypass air around the throttle plate. It’s essential for smooth cold starts, steady RPM at stops, and compensating extra loads from A/C or power steering. Built to OE specs for Toyota full-size platforms like Land Cruiser, Sequoia, and Tundra, it restores factory drivability and fuel efficiency 🚙.

Why you need it

Without precise idle air control, the engine can’t maintain a steady idle under changing conditions. This valve ensures clean combustion, reduced emissions, and quick start-up, hot or cold.

How it works ⚙️

The ECU commands an internal stepper/solenoid to open or close a pintle, varying airflow through a dedicated passage. More air raises idle; less air lowers it. Sensors feedback let the ECU fine-tune RPM in milliseconds.

When it fails ⚠️

Expect rough or hunting idle, stalling at lights, hard cold starts, high fuel use, and a Check Engine light (often IAC-related codes). Carbon buildup, worn pintle, or a burnt coil are common causes.

Tech tips ✅

Install on the throttle body with a new gasket, clean passages, check the harness and vacuum lines, then perform idle relearn as specified by Toyota.
