The O2 sensor is before the cat, the cat performance monitor (which looks like an O2 sensor) is after the cat.

Where is the 02 Oxygen Sensor before the cadalic converter on a 2006 Hyundai Santa Fe


Usually these are located on the exhaust manifold or just below the exhaust manifold and you should be able to see it in the engine bay. On V6 engines there will be one sensor on each of the 2 exhaust banks.
You will probably need to remove the engine cover to see the sensors on your exhaust.

If someone told you to replace these because you got a particular fault code I would be wary. A decent scan tool and basic diagnostics can show if the 02 sensor is working or not. Some faults often blamed on an 02 sensor are not due to faulty sensors.

I have a honda crv 2005. I got a P420 on it 12/31/13. I went to the dealer and did a diagnostic. They claimed I need a new converter (the most expensive repair, of course). They shut off the sensor and it...


There are a number of things that could be causing this p0420 catalyst efficiency code. The most common thing is the catalytic converter itself is no longer functioning properly. The other likely thing is the rear O2 (oxygen) sensor is no longer working properly. Other things could include exhaust leaks, damaged exhaust pipes, damaged O2 sensor wiring/connectors, plugged catalytic converter. The easiest thing to do first is a visual check of things. Visually inspect the exhaust system for leaks, check the catalytic converter for dents, holes, severe discoloration, and check for a rattle inside. If any of those syptoms are there, the converter likely needs replacement. To do a rattle check you need a rubber mallot to lightly tap the converter. If you hear stuff rattle in it then it will need replaced. Then, visually inspect the downstream O2 sensor (behind the converter). Check for broken wires, obvious faults, etc. If all that checks out, you'll want to check the operation of the O2 sensor. To do that, you'll need access to a scan tool or oscilliscope. Check that the waveform is pretty steady. If the reading fluctuates then the sensor is likely bad and will need to be replaced.

PO420 code for CR-V Honda 2002


p0420 is a catalytic converter efficiency code. It sets when thecm determines that the catalytic converter is no longer doing its job. The usual fix is to replace the catalytic converter. An O.E. or an aftermarket direct fit converter from a reputable manufacturer is your best bet. Lesser quality brands will leave your pocket book lighter to start but will cause more problems than they solve.

Mechanic said bank2 sensor1 is bad. I know my way around an engine but where would this be located on a 2002 Honda Passport LX


Saying 'bank 2' implies you have a V6 engine-bank 2 is the side that does not have #1 cylinder. Because you have a newer OBDII system, though, you have 2 sensors on each 'side'-before the catalytic converter and after, referred to as 'side 1' or 'side 2.- So your bank 2 sensor(2) are either before he cat or after, which one did he say you needed? Usually the Side 1 sensor needs to be replaced since it is the one that the engine computer uses to modify settings on that side of he engine-side 2 O2 sensor merely monitors the catalytic converter effenciency. If you determine where your second 'bank' is, and follow the exhaust out of the engine compartment to the catalytic converter, the O2 sensor is located there in that small space.
