In the 2003 Toyota Corolla, there are two oxygen sensors installed. Positioned just before and after the catalytic converter, these sensors are approximately the size of a spark plug and extend into the engine's exhaust system. Their main role is to measure the oxygen levels in the exhaust. By utilizing these sensors, the engine can adjust as needed for proper gas combustion and optimal performance. A malfunctioning oxygen sensor is one factor that can trigger the check engine light, so it's important to have them checked regularly. Keep in mind that if they aren't functioning properly, your car may not pass its annual inspection.
