Trouble code P0136 means: HO2S-12 (Bank 1 Sensor 2) Circuit MalfunctionThis means that your o2 sensor (oxygen sensor) after the catalytic converter is faulty. This can either be the wiring and circuit itself or it can be the actual sensor. (9 times out of 10 for me, it is the sensor itself). The wires are well protected and unless they've been messed with before they should never be harmed!
