I have now gone almost a week after disconecting the battery. I have not yet met readiness status on oxygen sensor or catalyst but also no CEL on yet either.
it seems to be taking a long time to complete the drive cycle?
I just checked for codes and found this P1081 see owners manual? What in the world does that mean? It did not produce any CEL but it is a present code.
Anyone know the exact conditions the catalyst and oxygen sensor tests are looking for? I am still hopeful to complete drive cycle with no check engine lights on. It seems to be taking a very long time to complete.
Please help if you can.
