2002 S60 CA CARB smog test readiness

blurat · Post by **blurat** » 18 Sep 2018, 12:47

Hi, my son is having trouble with his 2002 s60. Passes smog numbers but they say he has to drive a cycle to ready the sensors.

Did that still failed. Went to the ref in Elk Grove. Passed everything but the readiness part. The ref said take it to the dealer and they will reset the sensors.

Is this something that can be done with vida? I hooked up once and didnt see any codes or other information. If it can be remedied with Vida, what would I look for?

Thanks
C

VIDA can reset any error codes that may be in the system, but sufficient drive cycles will still have to be completed before it can pass a readiness check. The vehicle needs sufficient data sampled from various sensors before it marks them "ready." This can actually take quite some time (a week or more, even) depending on how the vehicle is driven, particularly for items like the EVAP system. VIDA doesn't do an OBD-II "Readiness" per se, but inexpensive handheld OBD-II readers will do this, and will show you which systems are not yet "ready".

Following this specific drive cycle is supposed to clear all the readiness checks, so it might be worth a shot:

Thanks for the info. He has driven 243 miles since the first fail. The ref passed the evap system, phantom black smoke, and all the numbers are good. Just the readiness.
Can this be caused by leaving your lights on all night and killing the battery?

Thanks again

Possibly - any time the car is off and the battery is disconnected or otherwise doesn't provide sufficient voltage, the OBD systemstats will be reset, essentially in the same way as if you had used an OBD code reader to reset the codes. Then your drive cycle starts over from scratch.

Only some codes reset. Many remain on these cars. But I don't know about readiness since I don't think that's a thing here, we can still reset codes outside the door of the inspection. The few who do this probably aren't considered a big issue.

Find out which ones arent setting and report back

The Evap is the most difficult. Doing any of the following can delay resetting EVAP..

Exceeding 60 mph
Using AC (more specifically cycling compressor)
More than 90% throttle request.

The car only tries three times for each 'drive' to go ready, then it gives up until the next day.

A dead battery will start the whole cycle again.

OK. Bought a reader that tells of readiness. All items in readiness test mode are OK or N/A. Which according to the instructions meand the item is good to go or not on this vehicle.
No check engine light.
Code P0420. catalyst efficiency below threshold is the only bogus reading. Bank 1..
Is this the fix with the spark plug spacer? At the ref, the vehicle passed all the numbers just this code I guess. It was 120 miles to the ref round trip so maybe if there was other non ready items they set?

Your thoughts?

.i once drove2400 miles before my Evap monitor went ready. My guess is your trip did the trick.

I’m not an expert on CARB but I didn’t think pending codes mattered. The car will often have pending codes, many codes have to repeat on several drive cycles before they are set and turn on the CEL.

Thanks for the reply. Im a bit leary to remove the stored code as he will have to redrive to ready all over again.
Some searching reveals ,or suggests, cleaning out the cat with a product called Catclean. One guy uses a gallon of laquer thinner.

At this point I think dumping something in the tank is easiest if it does the trick. If not, move on to the next suggestion/

I did a little google searching and you should not fail smog for any pending trouble code.

You can fail if you have a monitor not ready

You should hammer on the smog tech to pass if you pass emissions, have no CEL, and all monitors are ready.

There is also an exemption for the evap monitors not ready in CA which is documented in a thread in this forum, too.
