HO2S Heater Control Circuit High Bank 2 Sensor 2

Where it lives

For P0058, the sensor sits on the circuit this code reports. The description of P0058 puts it on bank 2.

Check these first

• A short to voltage in the Bank 2 Sensor 2 heater control wire
• High resistance in the heater element circuit raising the control voltage
• A failed heater element in the Bank 2 Sensor 2 oxygen sensor
• Corrosion or damage at the Bank 2 Sensor 2 connector
• A fault in the ECM heater driver circuit

What to do next

1. Check the control wire for a short to voltage
2. Measure heater resistance at the Bank 2 Sensor 2 connector
3. Inspect the connector and wiring for corrosion or chafing
4. Compare heater circuit voltage to the sensor spec
5. Replace the Bank 2 Sensor 2 oxygen sensor if the heater is faulty
6. Clear the code and retest
