Walker 215-2106 is an OE replacement fuel injection idle air control valve built to regulate bypass air around the throttle plate and keep idle speed steady. It is engineered for direct replacement service on applications such as Nissan Sentra and Nissan Altima, with factory-style electrical connection and OE-matched airflow control.

Key Features

• OE replacement idle air control valve for fuel injection systems
• Metal housing with steel finish for engine-bay durability
• Spade terminals, 2 male terminals
• 4 mounting holes for direct installation
• Gasket or seal included
• Matches OE-style pintle shape, stepper motor response, voltage range, and airflow control curves

Product Details

The Walker Valve Only line focuses on direct-fit replacement components for idle control service. Part number 215-2106 is designed to mount to the original throttle body or intake housing and connect to the factory wiring harness without modification. In normal operation, the IAC valve responds to ECU commands during warm-up, accessory load changes, and deceleration to maintain stable idle and reduce stalling. This makes it a practical choice for Nissan Sentra and Nissan Altima idle air control repair when the original valve is worn or contaminated.

This part cross-references Standard Ignition AC635 for the same application.

Common Symptoms Addressed

• Erratic or unstable idle speed
• Stalling at stoplights or during deceleration
• Hard starting after warm-up or cold start
• Check engine light related to idle air control performance
• Idle fluctuation when A/C or power steering load changes

Installation Notes

Verify connector style, mounting pattern, and throttle body configuration before installation. Clean the mating surfaces and inspect the throttle body passage for carbon buildup, since deposits can affect idle control performance. Confirm the gasket or seal seats correctly and reconnect the factory harness securely. For best results, clear any stored idle-related codes and perform the manufacturer-recommended idle relearn procedure if required.

Quality Assurance

Walker Products builds this idle air control valve as an OE-style replacement component with high-temperature-resistant materials and sealing against fuel vapors and moisture for underhood service conditions.
