would my hypertech programmer tell me if my 02 sensors are bad? Where would I see the MIL light ? would that light be on my gauges ?

 

The MIL (malfunction indicator lite) orCheck Engine lite lights up in your instrument cluster, hard to miss when it light up. As far as I know the Hypertech reads trouble codes, but does not show the actual data stream like a real scanner does.

 

well i don' t think my O2 sensors are bad, but i will replace everything else
