To replace a PO13502 sensor heater, first, disconnect the negative battery terminal to ensure safety. Locate the oxygen sensor associated with the code, typically found on the exhaust system. Unscrew the old sensor using an oxygen sensor socket, then install the new sensor by threading it in and tightening it securely. Finally, reconnect the battery, clear any diagnostic trouble codes, and test the vehicle to ensure the issue is resolved.
9 time out of 10, the heater circuit internal to the sensor has failed. Replace the sensor.
If it is saying that the heater circuit has failed then this O2 sensor has failed. The o2 sensors have tip heaters in them. These are irreplaceable. Replace the whole sensor. This particular sensor is located on the driver's side exhaust in front of the Catalytic Convertor.

To repair a fuel sensor heater circuit response, first, diagnose the issue by checking for any fault codes using an OBD-II scanner. Inspect the wiring and connectors for damage, corrosion, or loose connections, and repair or replace as necessary. If the fuel sensor heater itself is faulty, replace the sensor. Finally, reset the vehicle's computer and verify that the issue is resolved by conducting a test drive and checking for any new fault codes.
The heater in the oxygen sensor has failed. Its a good idea to replace BOTH oxygen sensors at the same time. If one has failed the other won't be lasting very long.
The P0141 code on a 1997 Ford Ranger indicates a problem with the oxygen sensor heater circuit for the bank 1 sensor 2. To fix this issue, first, inspect the wiring and connectors leading to the oxygen sensor for any damage or corrosion. If the wiring is intact, test the sensor itself and replace it if faulty. Additionally, check the fuse related to the oxygen sensor heater circuit and replace it if necessary.
Hi Every one Can you help meWhere Is the heater 02 sensor and heater circut fault sensor 1 for 1999 Honda Civic?
The Exhaust Manifold Oxygen Sensor needs to be replaced.
Bank 2 sensor 2 refers to the oxygen sensor on the passenger side of the exhaust system and after the catalytic converter. heater circuit is the oxygen sensor or the wiring going to it, it is what is called a heated oxygen sensor. Google image search oxygen sensor and that is what it looks like, and they can be a bear to get out.
