Hey, everyone. I'm pulling my hair out trying to get my 1999 S70 to pass the California smog test. Emissions aren't the problem. It's the stinking computer. Several months ago I disconnected the battery to clean the posts, and when I did that it reset all the computer monitors.
1500 miles later, three of the monitors -- the catalyst, evaporative, and oxygen sensor -- still aren't ready. I can have 2 "unready" monitors, but not 3.
My mechanic tells me the car isn't throwing any codes, so there's nothing to fix. I just need to keep driving it. Specifically, there's a 30-step drive cycle that will reset all the monitors (he gave me a copy), but it's been impossible to complete in Los Angeles traffic. Meanwhile, the DMV tells me that due to new legislation they can't extend my registration any more than 1 day and that the car is now illegal to drive.
So I'm not allowed to drive the car because it's not registered . . . but I have to keep driving it to get it registered
Faced with that, I took the car to the dealer this week and asked if I could pay them to complete the drive cycle. This morning, they called back to say they had to do the following before they could reset the monitors: replace the battery cables ($450), replace the main relay ($60), replace the evaporative valve ($90), and clean the throttle body ($220).
For those of you who know what all goes into resetting a monitor, does this sound plausible? Could these issues really being causing the monitors to remain unready? Seems odd, especially when the car isn't throwing any codes.
Thanks in advance.
