Detailed Description

Standard Ignition AC527 is an idle air control valve used to regulate bypass air around the throttle plate at idle. On supported Toyota Corolla, Toyota Matrix, Toyota MR2 Spyder, and Pontiac Vibe vehicles, this component helps maintain stable idle speed when the engine is cold, when accessories are engaged, or when the throttle closes. This part cross-references 2-16812 and 214-1101 for the same application. Standard Ignition AC527 is a practical replacement choice when servicing idle control concerns on 2000-2007 Toyota and Pontiac platforms.

What It Can Help Resolve

• Unstable or fluctuating idle speed
• Engine stalling when coming to a stop
• High idle after startup or during warm-up
• Idle speed changes when electrical loads are switched on
• Idle control faults related to air bypass regulation

Installation Notes and Tips

Verify connector style, hose routing, and terminal layout before installation. Clean the throttle body and adjacent air passages during service so the replacement valve can operate against a clear bypass path. Confirm vehicle-specific fitment by year and model before ordering, especially for Toyota Corolla, Toyota Matrix, Toyota MR2 Spyder, and Pontiac Vibe applications.

Quality Assurance

Standard Ignition supplies replacement ignition and engine management components for service applications, and AC527 is cataloged for direct replacement use on the listed vehicles. Confirm the part number AC527 against the original unit and vehicle application data for accurate selection.
