PO161 O2 Sensor?
Last couple of weeks I have been getting an intermittent CEL on my 2000 C280 with 44m. The light would go on for a few days then off for a few days. Borrowing a reader from AutoZone produced the code "PO161, Sensor heater circuit malfunction, Bank 2, Sensor 2".
This means the left (driver) rear O2 sensor needs replacing? Thanks, glenmore 1991 300CE 2000 C280 1990 LS400 |

Yes, that is correct.
