1999 S70 vs. California Emissions Test

How does it hold up with the California Emissions Test?

Here is some additional information from the EPA you can bring to the technician smoging your car if its running into readiness issues.

APPENDIX D

Manufacturers Known to Have OBD Readiness Issues

1996 Volvo 850 Turbo – Vehicles will clear readiness at key-off. There is no reprogramming available for this line of vehicles. These vehicles should be scanned for MIL illumination without regard to readiness status. Volvo Technical Service Bulletin #SB 2-23-0056.

1996-98 Volvo vehicles (excluding 850 Turbo) – These vehicles may have a high degree of “Not Ready” for catalyst and evaporative monitors due to a “trip based” design. Volvo has provided driving cycles in its service information to allow monitors to operate. These vehicles should be treated as other non-problematic vehicles. Volvo Technical Service Bulletin #SB 2-23-0056
