Paul Whiffin Posted June 28, 2011 Share Posted June 28, 2011 Hi chaps, Having a bit of nightmare with a 350Z with have here at the moment. The ecu light is on so we did a diagnostic check and it came up as O2 sensor 1 and 2 bank 1. We changed the O2 sensors and now the code is heater control circuit low bank 1. Anyone else had this before? Quote Link to comment Share on other sites More sharing options...
