EGR Vacuum Modulator | 3VZ-E (1988-95 4Runner / 1988-95 Pickup)

EGR Vacuum Modulator

For 1988–1995 Toyota 4Runner and 1988–1995 Toyota Pickup equipped with the 3VZ-E 3.0L V6.

Overview

This Standard EGR vacuum modulator regulates the vacuum signal supplied to the EGR valve using engine vacuum and exhaust backpressure. It fits 1988–1995 Toyota 4Runner and 1988–1995 Toyota Pickup with the 3VZ-E 3.0L V6.

The modulator is a separate service component from the main EGR valve and the electrically operated vacuum switching valve. It replaces the modulator without requiring a complete EGR valve assembly.

Key Features

• 3VZ-E EGR application: Matched to the factory V6 emissions system rather than the four-cylinder modulator configuration.
• Mechanical vacuum control: Uses vacuum and exhaust backpressure signals rather than an electrical connector.
• Four hose connections: Three upper vacuum connections and a separate lower backpressure connection.
• Common emissions fit: The same modulator serves Federal and California 3VZ-E applications.
