Hi there. Believe it or not, many of these codes can be cause by a faulty O2 sensor that has been allowed to continue without repair. The fault sounds like it is definitely a failed O2 sensor, but there could be an issue with the harness or ECM. This truly needs an inspection performed by a qualified technician. The codes could be related to the source O2 sensor for the particular related engine bank, but needs appropriate testing to avoid replacing unnecessary parts. Replacing parts without a proper diagnosis is like playing a game of darts; sometimes you get lucky, other times you get a really expensive bill. Your Mechanic has several available technicians that can assist you with a check engine light inspection.
