To diagnose this issue successfully you really need to have a scan tool to look at your O2 sensors and also your fuel trims...if the PCM sees the O2 millivoltage less than 200 mv for about 30 seconds the DTC will set...you’d be better off taking it to a mechanic especially if you don’t have a scan tool or a DVOM to look at the wiring !!

If you can find a diagnostic shop you you’d be better off...a “general” mechanic would just be changing parts and that can get expensive !!

The scan tool isn’t going to tell you what needs to be replaced but the person looking at the data it’s providing will be able to interpret that data...the low O2 sensor low voltage code isn’t a really hard one to diagnose but finding a good diagnostic tech is...contact your local Corvette Club in your area and see who is recommended...that is about the best I can do for you...did you do any mods or have any repairs done to the car recently ???... ie...headers etc ??....that would help !!...did you use OEM O2 sensors ??...not a good idea to use aftermarket ones on these cars.
