I've posted before about the problems experienced with my '96 900S Convertible which was proving very reluctant to set all the sensors "ready" as required to pass the Smog test.
To cut a long story short, the car ended up at the California Air Resources Board in El Monte, where they deal with vehicles having such problems. The nice aspect of this is that they investigated very thoroughly why the car was having so much trouble setting ready, and
any repairs or modifications they made they paid for.
1) They started off by replacing the resonator on the exhaust, which had
a slight leak.
2) They replaced the battery
3) They found that the coolant wasn't getting to temperature as quickly as
expected (it was taking at least 10 minutes, rather than the normal 5 minutes), so they replaced the theormostat, which fixed that
They tried following Saab's drive instructions for readiness, but had great difficulty getting all the sensors to set.
They then put it on a rolling road, and managed to set the sensors by
meticulously following the drive instructions. (They then quickly went
and smogged the car!)
They then un-set the sensors, cooled the car down (as required) using
a huge fan, and tried to set them again. They repeated this test several
times, to try to get a feel for which part of the drive cycle was so
critical.
Having done all that, and accumulated a lot of data, they are now in communication with Saab in an effort to identify why this is so difficult, and hopefully improve the ease of OBD settability for this vintage of 900 in the future for others.
Happily I now have my Saab back, fully smogged. It's been out of my possession for about 2 months.
