P0036 Volkswagen Code - HO2S Heater Control Circuit Bank 1 Sensor 2
Quick Answer
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. Common causes include Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2, Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 fuse, Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 harness is open or shorted. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0036 Volkswagen Description
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
What are the Possible Causes of the DTC P0036 Volkswagen?
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0036 Volkswagen?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Code 0036 03 Jetta 2.0 L gas. Does this code specify either the pre or post converter or do I have to get in and do more checking?

Hello, i have a 2006 Volkswagen Jetta 2.5 - I have an issue with my HO2S Bank 1 Sensor 2 - it says there is an open circuit. I could have possibly misplaced the fuse in the fuse box for it and thus the problem. i was wondering if you know a source where i can find the location of the fuse in my fuse box, im having a tough time finding the correct diagram. Much appreciated
-
OBDIITech is absolutely wrong in saying fuse 43, the 43 in the diagram represents the line 43 at the bottom of the wiring diagram where that bl/ro wire is connected with. There is no fuse to the rear O2 sensor as the wiring is direct from the ECM (J220). Replace your rear O2 sensor (B1 S2). BTW, I am a VW Certified Expert Level Tech with 20+ years experience and know how to read VW wiring diagrams!

Thank you for the the information. I should have researched more before posting the answer. I'll delete the information to avoid confusion.

Where is the oxygen sensor fuse for a 07 be rabbit 2.5 liter the code was at first part selinoid runs a lot better but now code came up bank1 sensor 1 o2 sensor but I still would like to know where the fuse is thank you.
-
I have a 06 rabbit replaced the o2 and still get code . Is it the harness or the 02 sensor ? I was thinking of testing the voltage do you know how to do this ?
