P0036 OBD2 Fault Code in Volkswagen - HO2S Heater Control Circuit Bank 1 Sensor 2
I recently received a Check Engine Light alert with fault code P0036, indicating an issue with the HO2S Heater Control Circuit for Bank 1 Sensor 2. The vehicle was brought to the factory dealership for service related to a malfunctioning running light on the right side. During inspection, they found a blown fuse. After repair and departure from the dealership, the Check Engine Light reappeared. I am concerned whether the technicians may have accidentally bumped or disturbed the fuse or wiring during servicing, potentially triggering the P0036 code.
It's unlikely that a blown fuse caused the P0036 code directly, but it's important to verify whether any fuses or wiring were physically disturbed during service. A thorough inspection of the relevant circuit and fuse box is recommended.
