2006 Camry, 4 Cylinder, Automatic, 185,000 miles.
My OBDII showed a P0420 error code and the problem was isolated to the post catalytic Oxygen sensor, which was replaced.
The error code was cleared after the oxygen sensor was replaced.
I have since driven the car for eight weeks and the OBDII catalyst monitor test will not complete. I have driven in excess of 2000 miles, driving the Toyota recommended driving profile many times, to no avail.
I have no OBDII error codes and all other monitor tests are complete, but the catalyst monitor test will not complete. I even disconnected the battery. After reconnecting the battery all OBDII tests, except for the Catalyst Monitor test complete in less than one day of driving!
I have driven the Toyota recommend profile to get the tests to complete with no positive results, just a lot of unhappy people on the highway!
Can someone please tell me how to get the ODBII monitors to complete?
I am in despite need for it to complete as my emissions test is due in several weeks and I will fail if I have any incomplete tests.
