You have to have access to a working vehicle - a rental, a loaner all these would fit the definition of your employment condition.

Look at the document that dynbin (?) posted - I think he made reference that there is a CARB ruling that non-ready monitors on Volvos can be ignored pre 1999?

I created a whole separate thread on this as I thought it might be important to CA guys...

:-)
Oh I'm aware my company probably wouldn't fire me for that issue, I'd just see if Cali would let me use it as leverage for a conditional pass.

My model is 2001, sadly, and I stress sadly... That CARB ruling is bunko for me. 2000 and older is only allowed evap to not be set.

I'm sorry if it seems like I'm being an info leach here, I go to school at night and I'm a family man with a single income family. Most of my time and money is spoken for, that's why this thread has gone on for so long! As I'm a baby do it yourselfer, my info search skills are limited to my limited, limitedness. :)

Thanks a lot for the responses btw. Much appreciated.

HCM, 2 Air, A/C, and EGR
OK - more info

Im not sure what HCM is??

I don't think you have Air injection on this car at all

The AC code is known to get stuck on these cars so that is a phantom

You don't have EGR on this car.

Make sure you have the right ECU - if someone has messed with that you are in big trouble for smog.
HCM I've come to find out is "heated catalyst monitor"... whatever that is. Ugh.

Thanks for pointing out that it's not air injected, one less to worry about. Just looked that up.

Again, nice to know I don't have an EGR! You are fantastic!

I am the second owner, so I'm unsure of the ECU. I have smogged this car before though. I'll have to check on that.

As for the AC code, I wonder if clearing the codes again and starting from scratch could fix that.

Thanks again. You're one of the good ones!

Evan - don't sweat starting out here. Some of us are passionate and post a lot like me, others who actually know stuff post a lot too

:-)

When a first poster writes a clear request for help outlining what they think, know, and symptoms we love that and don't care if you are going to join us or just lurk. It all helps others which is good.

Back to work. Im on a client conference call in the Amtrak station in NYP, listening to the client CFO think he adds value by reading his spreadsheet column entries. Literally. only about 35 more minutes of this, so Ill help someone fix there car while I listen

That HCM monitor is on your car. I think that aftermarket OXS might be a POS which doesn't have the right resistance on the heater circuit or maybe even the OXS itself. I hate throwing OXS into cars until you really know they are bad but Im leaning this way on this one, especially if it isn't OEM. The minute I hear splicing, I also get ill.

If it smogged before, forget the ECU. See my tagline :-)

Are you seeing monitors NOT READY or N/A Not applicable?

Keep all your papers of visits and receipts of inspection in your car in case Poncharello pulls you over for Smog - can you CA guys talk your way out of it if it isn't way overdue while you are in process?

Thanks for the reassurance. I've been on some forums (unrelated to cars) that rip you a new one for asking questions that sound like you haven't thoroughly searched the issue first.

I was kinda leaning on that downstream o2 being the HCM issue. It's not a crazy expensive part. In fact, in digging through the spare wheel compartment I found the original cut off head for that sensor, has the part number on it too. Just a bit hard to get to. I know I can tackle that within a couple of hours.

The monitors are reading N/A, but I think my reader uses not ready and n/a interchangeably, it's a low end reader. To avoid purchasing a new OBD reader right now, I'll head to autozone and have them check my codes. They do it for free. Is there a way to know if any of the other monitors don't apply to my vehicle? If there is I certainly am lacking the google skill for that issue.

My issue is that the car is way overdue. It's sat for a year with no driving. I used my brother's spare vehicle and as funds are always tight being a single income household, I've had a hard time collecting the tools/equipment to do the job. We've also had a crap year financially, just one disaster after another. My brother moved out of state on short notice and it's kind of forced me to have to tackle the issue in a short window.

This car is crazy... Just last week the door weather gasket came off, fluid in the rearview mirror burst, the interior, passenger front door handle shattered in my hand AND the oil dipstick broke in the tube when I took it in to get an oil change. I'm not sure I'll ever purchase another modern volvo again. A bulb went out too and when I attempted to change it out I noticed that the plug for it was melted... Whew! The older volvos I've owned were just tanks! This thing just gives me the sads.

That's better. I think a bunch of those monitors don't apply so you might' be close to being smog ready.

Fair warning , though. These are high end luxury cars , with expensive parts. They aren't cheap to run and too rare for there to be good quality aftermarket replacement parts, with a few exceptions

Alright. The car smogged. The monitors were ACTUALLY not applicable. Such a huge relief. So, to anyone who decides they want to take on the repairs of their Volvo by themselves... Buy the best OBD2 scanner you can purchase and get ONLY oem parts. Buy only OEM parts. BUY ONLY OEM PARTS!!! If you can't afford them, save for them. Sell your kidneys, blood or sperm for them. Take on a second or third job if you have to. Thanks a ton to you guys for the assist, this resource has been invaluable. Now to repair the dumb little cosmetic issues. Thanks again guys!

Glad to read the smogging went with positive success!

Depending the election, I may be driving something else and the volvo may be just a dwelling memory. :cry:
