Causes and Fixes P0136 Code: O2 Sensor Circuit (Bank 1, Sensor 2)

How to fix P0136 Code: O2 Sensor Circuit (Bank 1, Sensor 2)
The oxygen sensors monitor how much oxygen is burned off during combustion. The computer uses the information to adjust the air/fuel ratio mixture. They also monitor the catalytic converter.
A P0136 code is set when the computer (ECM/PCM) detects low, high, or no voltage on the Bank 1, Sensor 2 oxygen sensor.
Causes of a P0136 code include a bad oxygen sensor, wiring issues, exhaust leaks, and a damaged oxygen sensor connector.
Possible Causes P0136 Code:
Faulty 02 Sensor Bank-1 Sensor-2
Wiring - Open Short - Blown Fuse
