My car threw a P0430...what does that mean?

Vbp6US · 08-31-2013, 04:59 PM

I went to a mechanic shop which said my check engine light indicated a P0430 code. I don't know what that means other than it's an O2 sensor reference. I did some research and found out it's Bank 2 so here is my question:

How many o2 sensors are there per side? It says bank 2 but aren't there two per side? How should I troubleshoot which one is problematic if there are two per side?

Thanks

I see.

Are the two sensors completely different per side? Let's take the drivers side as an example

sensor1------[-cat-]----sensor2

Will sensor1 and sensor2 have the same part number or are they completely different? Will a sensor meant for a 2011 370z work for a 2009?

Thanks man.

There is a front set and a rear set,you can interchange the back 2 which each other and the front with each other but not front to back.

Thanks!
