Keep exhaust gas recirculation working the way Toyota intended with the Standard Ignition EGR Vacuum Modulator (VS105). This vacuum modulator drops in as a direct-fit replacement for the listed applications: the 1995-2000 Toyota Tacoma [L4-2.4L], 1995-2004 Toyota Tacoma [L4-2.7L], 1996-2000 Toyota 4Runner [L4-2.7L] and 1996-1998 Toyota T100 [L4-2.7L].
The modulator senses exhaust backpressure and regulates the vacuum signal sent to the EGR valve, so the valve opens the correct amount for the engine's operating conditions.
Signs the modulator may need replacing include rough idle, engine ping/knock, or an EGR-related trouble code. These symptoms can have other causes, so diagnose the EGR system before replacing. If a faulty vacuum modulator is the cause, this VS105 replaces it.
Interchange: Manufacturer part number VS105.
