Hello. After getting a random DTC76 code, I've been looking into checking the O2 sensors of my '99 VT L67. Today I cleaned the ground connections for the sensors, reset the PCM and went for a drive. When I got back I checked for codes (all good) and then logged the voltage of each sensor while holding the engine at 2k rpm. I've read that the sensors should contantly alternate between 100mv and 900mv, which it seems they do. At idle however, they both stay steady at around 800mv. As I don't know much about these sensors, I was just wondering if someone else could have a look at the graph to see if all is good. I can provide more readings if needed. Thank you for any help.
