All you need to know about the lambda sensor and exhaust

· The lambda sensor, also called an oxygen sensor, is a small probe located on the car exhaust, between the exhaust manifold and the catalytic was developed by Volvo in the 70s.. If you own a newer car, it will be equipped with 2 lambda sensors. In that case, the second sensor will be located right behind the catalytic converter.

P0420 — Diagnose catalytic converter and oxygen sensor ...

· If it sees that behavior, it knows the catalytic converter and the oxygen sensors are operating properly. However, if the oxygen sensor doesn’t switch rapidly during the test, the ECM will set a downstream O2 sensor trouble code. NOTE: This is why a P0420 trouble code is almost never a bad oxygen sensor — because the ECM has already tested the downstream sensor. If it isn’t responding ...

O2 Sensors Catalytic Converter Diagnostics | Car OBD ...

· o2 sensors catalytic converter diagnostics Converters typically fail one of two ways: they get too hot, melt and plug up, or the catalyst becomes contaminated and useless. Diagnosing a plugged converter is fairly easy, but diagnosing converter efficiency requires tapping into the OBD II system with a scan tool to check for codes and to compare the upstream and downstream O2 sensor …

Two Oxygen Sensors Monitor a Catalytic Converter ...

It’s done using two oxygen sensors. Catalytic converters begin their scrubbing of the exhaust stream by separating oxygen atoms from nitrogen oxide (NOx) molecules created during the combustion process. These freed oxygen atoms are then available for carbon monoxide molecules to grab to become carbon dioxide, and for unburned hydrocarbon molecules to split apart and bond to (the combustion ...

Catalytic converter vs O2 sensor Maintenance/Repairs ...

To the original question: The only way the ECU knows a cat is bad by the readings it get from the O2 sensors. A bad O2 sensor will indicate that the catalytic converter is bad. If the code indicates a bad cat…then further tests need to be run to determine if it’s a bad O2 sensor or a bad cat. Good mechanics know how to do this.

P0430, o2 Sensor or Catalytic Converter?? | EricTheCarGuy

· I know that this code can either be caused from a bad catalytic converter or a bad o2 sensor. His car has four o2 sensors. How would I go with testing these o2 sensors? I know 2 of them are supposed to steady while the other two are supposed to rapidly switch. In my case which one should I be looking at? Also if the o2 sensor is good then which cat would I be checking? Thank you in …

· The rear oxygen sensor (the one behind the converter) monitors how much oxygen is coming out of the converter at any time. A healthy converter will use a lot of oxygen, and so the rear oxygen sensor will see that there is little oxygen coming out of the back of the converter. In this situation, the "check engine" light will not come on to indicate catalytic converter failure, because all …
