Oxygen Sensors

Your Toyota has an oxygen sensor that is an important component to maintain.The job of the sensor is to measure the level of oxygen that is in your exhaust gases that leave the engine. These numbers get sent to the Powertrain Control Module (PCM) to help determine what the correct air to fuel ratio should be for your engine. The oxygen sensor is located in the exhaust system. It is responsible for allowing your fuel injectors to work efficiently with your engine, which in turn helps to control emissions. The oxygen sensor, to say the least, plays a big role when it comes to the amount of air and fuel that your vehicle has. If the oxygen sensor is going bad or starts to fail, it can cause a negative impact on your engine performance as well as the emissions coming out of your vehicle. There are a range of signs to look for that can indicate wear and tear on the oxygen sensor. The check engine light could come on if it wears out, or you could experience rough engine idles or misfires. Shop for Toyota oxygen sensor replacements here on our site.
