P0036 – Heated oxygen sensor 2, bank 1, heater control -circuit malfunction
DTC P0036 is an OBD-II code that refers to a malfunction in the Heater Control Circuit of the oxygen sensor. It indicates that there is a problem with the electrical heating element of the oxygen sensor, which can affect its performance. The code typically relates to the Bank 1 Sensor 2 oxygen sensor, which is located after the catalytic converter.
Sensor 2, located after the catalytic converter(s), monitors the performance of the converter in cleaning up the exhaust gases, while Sensor 1 measures the oxygen content in the exhaust stream before it reaches the catalytic converter.
Fixes for OBD-II Code P0036
To fix the P0036 OBD-II code, you can take the following steps:
- Inspect the wiring and connections: Check the wiring harness and connectors associated with the oxygen sensor Heater Control Circuit. Look for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring or connectors.
- Test the oxygen sensor: Use a multimeter (read more) to measure the resistance of the oxygen sensor’s heating element. Compare the reading with the specifications provided by the manufacturer. If the resistance is out of range, replace the oxygen sensor.
- Check the fuses: Verify that the fuses related to the oxygen sensor heater circuit are intact. Replace any blown fuses if necessary.
Note: It is recommended to consult a qualified mechanic or refer to the specific repair manual for your vehicle to ensure proper diagnosis and repair procedures are followed.
