Meanwhile, downstream o2 sensors monitor oxygen content just like the upstream sensors. It tracks the level of unburnt gas in the emissions released by the cat; If these codes appear, there may be an issue with the downstream sensor. Web oxygen, lambda, or air/fuel sensors are a critical but ofttimes overlooked component of fuel injected engines. Web an upstream o2 sensor detects oxygen content so that the computer can adjust the fuel injector pulse width to improve fuel economy and ensure that the engine runs properly. Web a catalytic converter acts as an oxygen battery. Web as simple as that. If the downstream o2 sensor switches too often, it indicates that when the there is a lack of oxygen. The downstream o2 sensor is on the opposite side of the catalytic converter. A leaky exhaust valve can do the same thing, allowing unburned fuel to pass.

Web summary so, what does a downstream o2 sensor do? If these codes appear, there may be an issue with the downstream sensor. Web heated oxygen sensors are less prone to contamination, as their internal heat source allows them to be placed much farther downstream than unheated sensors. Web an upstream o2 sensor detects oxygen content so that the computer can adjust the fuel injector pulse width to improve fuel economy and ensure that the engine runs properly. Web as simple as that. If there is too much o2 the catalytic converter will be running too hot. Modern vehicles have both an upstream and a downstream o2 sensor. One of the most common signs of a faulty oxygen sensor is an illuminated check engine light on your dashboard. Web summary so, what does a downstream o2 sensor do?
