Have 3 codes.
PO030 heated oxygen sensor heater control circut bank 1 sensor 1.
PO134 Heated oxygn sensor no activity detected bank 1 sensor 1
PO135 Heated oxygen sensor malfunction bank 1 sensor 1
two questions. which sensor is bank 1 sensor 1? And would just changing the sensor fix the issue?? or do i have something else going on with the heater circut??
