I bought my car with the aps TT, its an 06 and the kit has about 8k miles. Now I have a p2a00 engine code, which refers to the 02 sensors. Question is, do the aps tt kit come with after market o2 sensors or does it use the stock o2 sensor?

 

It should just be using the factory sensor....my greddy kit just uses the stock ones.

 

oh ok that answers everything, thank you.
