I have a 98 V70 T5. It did not pass the smog test (California). Needed to do some adjusting and replaced an O2 sensor. I have driven the car for 30 miles but the computer has not recored any data so I cannot retest. How long / how many miles does it normally take before the computer records the new info?

I sure am glad we do NOT have inspections anymore.

Volvos are also exempt from up to 2 readiness monitors, and at that time, they may perform a tailpipe test.

I was able to complete the drive sequence. Tough time finding a streach of road that works for this. Roads and traffic in Los Angeles are too congested.

However it worked. Thanks, for the help!
