Aaargh! Smog test failure / Warning / How many cycles?

[e9999]

FWIW it took forever to get my readiness code for the EGR system to be marked okay. Took about two weeks, and my truck is my daily driver, and I drove it around plenty trying to get the two required drive cycles in.

oh, great... not what I wanted to hear... But then seems like the PRK will allow 2 incomplete self-tests per above so maybe still OK...


who would have thought disconnecting the damn battery before a smog test would be so much trouble...

Can it send commands? If so, might be able to do like on the SCII page, that I linked.

no, can't do that.
Amazing that the Scangauge II has to go through all this hexadecimal decoding to find readiness status.

What does that mean? Thread?

Thread pending getting my truck back from having it's new exhaust installed. I may write up a thread sans pics, and then add 'em later. Not tonight though, maybe tomorrow....

The cheap reader I bought (for about $100) from Wally world does ready status. Shucks sells the same one.

I'd be awfully tempted to buy one, and then just return it.

I will confirm that my EGR (insufficient flow) code took 1-2 weeks to clear, though I don't get up to freeway speed for very long, or very often. It then came on about 2 weeks later, went away the same way. Hasn't come back for the last few months.

that time of year again...

Got myself a better Acton reader with monitors status display this time.
Had disconnected my battery for a lengthy trip away. When I powered up again it read 4 incomplete monitors (forgot which, sorry, but I think it may have been the O2 ones plus cat and maybe something else).

Interestingly, a 5 miles city trip with only a couple minutes, if that, of 35-40 mph took care of 3 of those but the *Catalyst* monitor did not set to ready after that nor after the reverse trip home.
Will try and do a bit of freeway driving to see if that does it for the Cat monitor, per the diagram above.

You smog check every 2 years?

Here it's every year and $39 pass or fail, unless it's older than 25yrs or disel in which case its a $15 safety check.

yes, 2 years, and about $50

Never did learn did you

well, 2 more short trips of about 6 miles each with a good chunk on the freeway at 60 did it. All monitors ready now.


So, if you were wondering, a total of 4 trips of about 5 miles each reset all 4 monitors that were tripped/left over by the battery disconnect. Not too bad actually.




Junk, wth? long time no read, man!

Junk - glad to see you still lurking you futher mucker!

Well, yesterday I reconnected the battery after replacing the head gasket and tying up some loose ends. I thought I might need a freeway drive this morning, but after a total of about three 5 mile drives on surface streets (I don't think I got up to 50mph) yesterday and today, on the fourth time I started the rig, the scan gauge showed -Ready-. Looks like my EGR, throttle body, intake manifold cleaning might have fixed my PO401 that was almost constant. I will know after the next freeway jaunt, as that was a sure way to set it off, before.

Am feeling the pain here on the smog tests. May I suggest that there are still some counties in California that do not require the smog test except on sale of the vehicle. Am fortunate to live in Siskiyou County, no smog tests after you buy your vehicle new or used! So maybe find an address you can use to register your LC in one of those counties.

Also there is a little known work around the smog it to sell it drill; if you sell you car to a relative no smog check is required.`
