Services Performed
- P0420-Catalyst system low efficiency bank 1 P0011-Intake cashaft position system performance. Monitored both bank 1 oxygen sensors-sensors mirror each other, indicating a failed catalyst. Also noted and 1 upstream sensor is switching slowly. Recommend replace bank 1 (firewall side) catalyst and upstream oxygen sensor. Engine oil is clean and full, LOF was recently performed(about 100 miles). Test drove while monitoring vvt data-desired and actual camshaft angles match. Code has passed monitor 3 times since it set, suspect low/dirty oil caused this to set. Recommend clear code and monitor.
- Replaced bank 1 catalytic converter. Cleared codes, test drove-ok.
