What Does The O2 Sensor After The Catalytic Converter Do
What Does The O2 Sensor After The Catalytic Converter Do. Post cat o2 behind the cat should read be fairly constant, if the catalytic converter working properly. Cars made in 1996 and after are required to have a second oxygen sensor that is located below the catalytic converter.
The o2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine. Show activity on this post. 1 of 2 go to page.
Oxygen Sensors, Commonly Referred To As O2 Sensors, Are Part Of Your Vehicles Emission System.
The rear oxygen sensor installed after the catalytic converter is called ‘downstream’ or sensor 2. Specifically, that it plays no role in engine mixture control. The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter.
The Purpose Of The Downstream, After Converter, Sensors Is To Monitor The Quantities Of Harmful Exhaust Gases Flowing Into And Out Of The Catalytic Converter To Ensure The Converter Is Working Properly.
The front oxygen sensor before the catalytic converter is usually called ‘upstream’ or sensor 1. There is a smell its the oil burning off the can, the label adhesive burning, particles in the exhaust getting warm and other smells. What is an o2 sensor?

If you notice that you are spending more on fuel than normal, it could indicate a sensor failure. In fact, some cars have as many as four oxygen sensors. What does the secondary o2 sensor really do?
Downstream O2 Sensors Do Not Affect Engine Performance.
To test the health of the catalytic converter. Anyone who tells you there is “no smell” from a fresh cat has never fitted one as until its run a few times there will be residues insode. (o2) oxygen sensor failure, can cause catalytic converter, meltdown.

Can a defective o2 sensor affect fuel economy? Too rich and the catalyst can melt down. If your car begins to stall or jerk, the culprits could be the o2 sensors and the catalytic converter.
