P0134 Bank 1 Sensor heater circuit malfunction

This is the job of the ECM, which is too look for open circuit, short circuit and grounds,rationality and irrationality, what you have set is a open circuit. These condition are detected by the ECM within the first ignition cycle. you may just need a A/F sensor or what is reffered to as a 02 sensor for Bank 1, double check see if the 02 sensor on Bank 1 which is the rear, may have been disconnected
