What Does The O2 Sensor After The Catalytic Converter Do
What Does The O2 Sensor After The Catalytic Converter Do. How to cheat the o2 sensors after catalytic converter removal ? One sensor is located closer to the exhaust manifold and the other one is located closer to the muffler.
Specifically, that it plays no role in engine mixture control. Both of these o2 sensors are located on the exhaust pipe. A second oxygen sensor is mounted downstream or behind the converter to compare oxygen levels in the exhaust before and after the converter.
The O2 Sensor Is A Part Of The Emissions System That Monitors And Regulates The Proportion Of Oxygen In The Exhaust.
A second oxygen sensor is mounted downstream or behind the converter to compare oxygen levels in the exhaust before and after the converter. This o2 sensor monitors the operating efficiency of the catalytic converter. With that being said, normally the pre cat o2 is more important but the after cat o2 could also fail an emissions inspection (dtc).
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.
The downstream o2 sensor in 3008 is located further down the exhaust system, after the catalytic converter, and is responsible for measuring the level of pollutants passing through the catalytic converter. Specifically, that it plays no role in engine mixture control. Open loop uses predetermined maps for fuel and timing until the o2s and cats have reached a specified temp then switches to closed loop where the computer uses o2 and tps, map, and/or maf sensor info to control fuel injector pulse width and ignition timing curves(which also use knock sensors, again automotive theory, not sure on bikes).
Sensor 2 Is The Sensor That Comes After The Catalytic Converter And Is Mainly Used For Onboard Emissions Testing.
So the article is telling you to use the post o2 sensor reading to determine if the misfire is due to a lack of fuel (clogged fuel injector, vacuum leak, etc), or too much fuel (spark plug didn't fire so none of the fuel was ignited and is. Post cat o2 behind the cat should read be fairly constant, if the catalytic converter working properly. Is it the o2 sensor or the catalytic converter?
Both Of These O2 Sensors Are Located On The Exhaust Pipe.
There is a smell its the oil burning off the can, the label adhesive burning, particles in the exhaust getting warm and other smells. People have often stated that the oxygen sensor installed behind the catalytic converter in a common gasoline engine setup has only one function: Downstream o2 sensors do not affect engine performance.

This sensor allows the engine computer to constantly adjust the amount of fuel sent to your engine, assuring proper combustion and the best performance and emissions. Discussion starter · #1 · apr 12, 2012. The rear oxygen sensor installed after the catalytic converter is called ‘downstream’ or sensor 2.
