Toyota Yaris GR and Corolla GR Dump Valve
Toyota Yaris GR and Corolla GR Dump Valve
This Blow Off, or Dump valve, has been developed for the Toyota Yaris GR Turbo engine that has the electronically controlled bypass valve (OE Part no. 7.04654.08). It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred. Unfortunately, the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this. This prevents the diaphragm from sealing.
