P0136 Heated Oxygen Sensor Circuit High Voltage (bank 1, sensor 2)
Right Bank Heated Oxygen Sensor (rear) Circuit
Check Conditions
3 minutes or more have passed since the startingsequence was completed. Right bank heated oxygen sensor (rear) signal voltage has continued to be 0.15 volt or lower. Engine coolant temperature is higher than 76°C (169°F). Engine speed is higher than 1,200 r/min. Volumetric efficiency is higher than 25 percent. Monitoring time: 7 seconds.
Judgment Criteria
Input voltage supplied to the PCM interface circuit is higher than 4.5 volts when 5 volts is applied to the right bank heated oxygen sensor (rear) output line via a resistor. The PCM monitors for this condition once during the drive cycle.
- Right bank heated oxygen sensor (rear) failed.
- Open circuit in right bank heated oxygen sensor (rear) output line.
- Open circuit in right bank heated oxygen sensor (rear) ground line.
- PCM failed.
