1) P0141 O2 Sensor Heater Circuit Bank 1 Sensor 2
2) P0401 Exhaust Gas Recirculation Flow Insufficient Detected
3) P0441 Evaporative Emission System Incorrect Purge Flow
For the second and third codes what would cause that? Do the problems stem from the O2 sensor? Unfortunatly I failed an inspection because of these and I did not even know there was a problem because the check engine light bulb burn out.
