Keep your engine idling steady with the Standard Ignition Idle Air Control Valve, MPN AC527. It installs as a direct-fit replacement for the 2003-2006 Pontiac Vibe, 2005-2007 Toyota Corolla, 2003-2007 Toyota Matrix, and 2000-2005 Toyota MR2 Spyder.

An idle air control valve regulates the amount of air that bypasses the throttle plate, allowing the engine control module to hold a stable idle speed under changing loads such as cold starts, the A/C compressor, or accessories switching on.

  • Idle air metering: Controls the volume of bypass air around the throttle plate so the ECM can maintain the commanded idle speed.
  • Direct-fit replacement: Designed to install in place of the original idle air control valve on the listed applications.
  • Restores normal idle control: If a failed idle air control valve is the cause of your unstable idle, this replaces it.

Signs this part may need replacing include a rough or fluctuating idle, stalling at stops, idle surging, or hard starting. These symptoms can have other causes, so diagnose the source before replacing.

Manufacturer part number AC527.
