After that you will have to rerun the o2 sensor tests in order to check if the failure still exists. In case it does, you will have to perform the pinpoint tests as mandated by the manufacturer.

Also check the o2 sensor heater circuit for any issues. Also measure the resistance of the Oxygen sensor bank 1 sensor and replace the oxygen sensor and wiring if found faulty.

In the end clear everything and conduct a test to check for further faults.

Common Mistakes When Diagnosing The P0147 Code

Common mistake that you are likely to commit while diagnosing this error code are many so make sure that you check the O2 sensor wire harness cover for contaminants entering into the covering that can short the sensor heater circuit. Also check the O2 sensor for oil or coolant contaminants that can be a potential cause behind the short circuit in the sensor circuit.
