O sensors and Cat conversion bank 2
 

Hello All,

I have a 2000 Porsche Boxster with approx. 89k miles on it. The check engine light came on and I bought a Duremetrix kit to find out what was going on.

I have seen a couple of post about the O sensors but not one quite like mine and since the catilytic converters are kinda spindy, I was hopeing to get some help.

The actual codes that the software found was as follows:

P1128 Porsche fault code 360 - Oxygen Sensing adaption (idle range bank 1)
P1130 Porsche fault code 361 - Oxygen Sensing adaption (idle range bank 2)
P0430 Porsche fault code 45 - Cat conversion bank 2 (exceeds limit value)

Is their anything I can do to verify what I need in order to take care of this?

Thanks,
Chris

I had the same problem as of this week, it may be the MAF that causes that. The shop that I took my car, had Porsche diagnostic computer and he check each individual O2 sensors voltage and did not see any problem with it. O2 and MAF are all expensive parts, so you may want to be sure that you are replacing the right part.

Do you have aftermarket cold intake on this car (like EVO)?

Thanks for the reply kias@tampabay.rr.com.

I know and so are the catalitic converters (ouch)

So what did your shop say about your car. Is your check engine light still on? Did they clean the MAF sensor or the O sensors?

This car is completely stock. I have made no modifications. The only items I have replaced is the coolent tank located in the truck as well as the water pump but neither of these items should have an effect on the o sensors or catalytic converters.

Thanks for the help!
