What is your question?
Have done everything to appease this code...even replaced the newly replaced Bosch 02 sensor with the Volvo preferred 02 sensor and still the light comes on. Can't smog it so can't complete the registration...have put too much money in out and now I NEED to know what the problem is!!! HELP
Both sensors have been replaced. And I mean by well-respected professional mechanics. We are all stumped.
