In a Toyota Yaris, you can locate the EGR valve at the front of the engine on the piping in front of the valve cover. Its role is to recycle exhaust gases back into the engine to improve performance based on the engine's workload. If you experience issues with the EGR valve, such as poor performance, misfiring, or stalling at idle, it may indicate a lack of air reaching the engine. Additionally, a check engine light on the dashboard will likely illuminate, signaling a problem that can be diagnosed using an OBD II scan tool to identify faults with the EGR valve.
