The 2003 Toyota Corolla's EGR valve connects to the engine's intake manifold. This component, known as the exhaust gas recirculation valve (EGR valve), plays a crucial role in the vehicle's engine management system. It redirects precise amounts of exhaust gas back into the engine intake system, enhancing engine performance, cutting down on fuel usage, and lessening NOx emissions. If the EGR valve malfunctions, it can disrupt the flow and function of the EGR system, resulting in issues like power loss, slower acceleration, and decreased fuel efficiency. The valve may get stuck in the 'open' or 'closed' position due to the accumulation of soot, carbon residue, and fuel contaminants.
