What Should Downstream O2 Sensor Read
What Should Downstream O2 Sensor Read - A leaky exhaust valve can do the same thing, allowing unburned fuel to pass. One of the most common signs of a faulty oxygen sensor is an illuminated check engine light on your dashboard. The downstream o2 has only one job, that is to monitor the catalytic converter. Web unlike the “upstream” o2 sensors that are located in the exhaust manifolds to monitor the engine’s air/fuel ratio, the downstream o2 sensors are used primarily to monitor the operating. 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. Downstream o2 voltage averages about 0.75 (but of course bounces around like an o2 should) upstream 02 voltages averages 0.3v can a bad cat make the second o2 sensor read. Web a catalytic converter acts as an oxygen battery. 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. It tracks the level of unburnt gas in the emissions released by the cat; The voltage will drop a bit at idle and raise a little when running but should always be stable and not varying like the front sensor.
Web the downstream sensor examines the amount of pollutants flowing through the catalytic converter. The downstream o2 sensor is on the opposite side of the catalytic converter. Web answer (1 of 2): Whatever setup you have the last o2 sensor should show an o2 reading that corresponds to having very little o2 left in the exhaust. And that includes check engine light. The downstream o2 has only one job, that is to monitor the catalytic converter. Web the sensor will trigger a catalyst inefficiency check engine code, indicating to the driver there is an engine issue. A leaky exhaust valve can do the same thing, allowing unburned fuel to pass.
