Hello there.
The heater control circuit high code for bank 1 sensor 2 typically indicates a problem with the heater circuit of the oxygen sensor located downstream (after) from the catalytic converter. Here are the general steps to fix this issue:
1) Check the wiring: Start by checking the wiring and connectors of the oxygen sensor to ensure they are not damaged, corroded, or loose. Repair or replace any damaged wires or connectors as necessary.
2) Check the fuse: Next, check the fuse for the heater circuit. If the fuse is blown, replace it with a new one of the same rating.
3) Check the relay: If the fuse is not the problem, check the relay that controls the heater circuit. You can use a multimeter to test the relay's resistance and continuity. If the relay is faulty, replace it with a new one.
4) Replace the oxygen sensor: If the wiring, fuse, and relay are all in good condition, the issue may be with the oxygen sensor itself. In this case, replace bank 1 sensor 2 with a new one.
5) Clear the codes: After making the repairs, clear the diagnostic trouble codes (DTCs) using an OBD-II scanner. If the repair was successful, the code should not return.
If you are not comfortable with these steps or do not have the necessary tools, it may be best to consult a professional mechanic. Have a nice day!
