2002 Toyota Tacoma DLX 3.4L MIL Lamp on VIN: 5TEWN72NX2
P0136: Heated Oxygen Sensor (Bank 1 Sensor 2) Circuit Malfunction. Thanks in advance - code appeared after toyota replaced the frame - tested heater & ground circuits - ok - customer replaced o2 sensor with factory sensor. Does anyone know of a ground wire that toyota may have left off somewhere to cause this issue ?
