Idle air Control Valve 22270-21010 For Scion XA XB Toyota Echo 1.5L 2000-2006

Idle Air Control Valve for Scion xA xB / Toyota Echo 1.5L

This idle air control valve (IAC valve) regulates the engine idle speed by metering air flow through the bypass passage. It is designed for Scion xA, xB, and Toyota Echo models with the 1.5L engine from 2000 through 2006, serving as a direct replacement for OEM part number 22270-21010.

Overview

This idle air control valve precisely adjusts bypass airflow to maintain a smooth and stable idle under all conditions. It works with the engine computer to compensate for load changes such as air conditioning or power steering. This idle air control valve is a direct replacement for the original unit on compatible Toyota and Scion applications.

Specs At A Glance

Good To Know

Q: How do I know if my idle air control valve is failing? A: Common symptoms include rough or fluctuating idle, stalling when the engine is cold, or a check engine light with an IAC-related code. Replacing the valve with this unit often resolves those issues.

Q: Is the idle air control valve difficult to install? A: Installation is straightforward for most DIYers: locate the valve on the throttle body, remove the electrical connector and two bolts, then install the new unit. Ensure the gasket surface is clean for a proper seal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
