- Faulty HO2S-11 Sensor
- HO2S-11 Sensor harness is open or shorted
- HO2S-11 Sensor circuit poor electrical connection
Scanners are a smart diagnostic tool but can be very dumb at the same time, yes it is saying that there is a problem at the O2 sensor, but you have to look a little deeper into the problem this code is for an open circuit or poor connection and not necessarily a faulty sensor, so you need to check all connections for loose or corroded connections and do a pin out from the sensor back to the ECU to look for open circuit or high resistance, start here.
