Walker Products Fuel Injection Idle Air Control (IAC) Valves are OE Replacement components that regulate the amount of air bypassing the throttle plate to maintain stable engine idle under varying conditions. Controlled by the engine control unit (ECU), the IAC valve adjusts airflow during engine warm-up, load changes (like A/C or power steering use), and deceleration to ensure consistent idle speed and prevent stalling. Each Walker IAC Valve is engineered to match OE specifications for pintle shape, stepper motor response, voltage range, and airflow control curves. Constructed with high-temperature-resistant materials and sealed against fuel vapors and moisture, these valves are built to withstand the harsh environment of the engine bay. Designed for an exact OE fit, they install directly into the original throttle body or intake housing and connect seamlessly with the factory wiring harness. Symptoms of a failing IAC valve may include erratic idle speed, stalling, hard starting, or illuminated check engine lights. Whether addressing drivability issues or performing a routine fuel injection system service, Walker IAC Valves provide precise idle control, improved cold-start performance, and restored engine stability across a wide range of domestic and import applications.
Characteristics include:
OE Replacement Calibration: Matches factory specifications for pintle movement, voltage response, and idle airflow control logic.
Built for Long-Term Reliability: Designed with precision components and sealed housings to withstand heat, vibration, and fuel vapor exposure.
Exact OE Fit: Installs directly into the throttle body using factory connectors and mounting points—no wiring or modifications required.
Restores Idle Stability: Eliminates rough idle, stalling, and hard starting caused by faulty or sticking IAC valves.
Controls Idle Airflow: Regulates bypass air around the throttle plate for stable idle and smooth engine operation during warm-up and load changes.

This my second time buying from Partspionner.ca great parts quality parts fast shipping to your door no need to wait on parts counter for minutes save gas ;)
I had an excellent experience ordering from Parts Pioneer, my order was placed and shipped quickly and received. Excellent customer service, I will definitely use them again when needed and let many of my friends know about Part's Pioneer
The site was very easy to use. When I emailed with a question the response came quickly. I appreciated that you verified that the parts would fit my vehicle. I will use the site again.
La livraison se fait en un temps record, malheureusement il y a eu un erreur de pièce, par contre un service très professionnel, facile d'accès et dans ma langue natale..... Le retour est accepté sans frais. Tout les professionnels dans le domaines de la mécanique savent que des erreurs survient aléatoirement au niveaux pièces un jour ou l'autre, pas très agréable mais la ou ce joue la qualité du service est le service après vente et je peux confirmé la compétence de l'équipe Parts Pionner... Merci à l'équipe
Toujours en attente du ticket de retour mais j'ai confiance dans leurs bref délais...
