Which sensor would I replace..... My car flash this code p0430..... Car has 200000+ km so it's due for replacing thanks

 

Bank 2 is the front bank. It might not be the sensor(s): it could be a bad catalytic converter or even an exhaust leak. Test the sensors first. If the sensors are good, replace the cat.

 

I'm have rv6 HFC ..... Never had a cell come up for about 3 years with the HFC
Thanks

 

That doesn't really change anything. The good news is that the RV6 converters come with a lifetime warranty from the manufacturer (can't remember who it is). Try resetting the codes first. If it comes back, look for exhaust leaks near the front cat. If there is no exhaust leak, check the bank 2 (front of car) downstream (lower) O2 sensor voltage. I don't have the specs on hand, but basically it's either the sensor or the converter that's bad. So if you test the sensor and it's good, then you know the converter is bad.

 

so reset my code ......... car hesitates during acceleration from stop , high speed is good but no light until yesterday and code P0430..... didn't change anything just reset my code this is what my diagnostic tool read
