At idling speed the upstream reads around .300v -.475v , while the downstream reads 1.300 to 1.450 after a couple minutes of run time from cold. I looked at readings from the purge while idling,and there was small voltage changes(just did not write them down or remember them). Also why would the purge solenoid not throw it's assigned code or pending code. Yes I am an OLD school tech and with all the computer check capabilities , I would expect a proper code for a system like that. NOT trying to argue but I have been wracking my brain on this one and incurring my daughters wrath, as I said that this car seemed to be pretty good and turns out there have been a number of small things to maint/repair that she did not expect to have to do.

Also I can download the info from the scanner to my PC, BUT am not confidant with trying to link from that file to the site. I am not that big into PC skills and take the old "type it out route". Hence no media and such. LOL

One issue at a time!
Will your Upstream O2 respond to rich/lean conditions? You can test with adding propane(rich) and vacuum leak(lean)??

Without the B1S1(presume you have a 4I, not a six) switching properly you are restricted on what the ECU can do..
Your reported readings indicate either a dead/lazy O2, or a lean condition.

Not sure why the B1S2, would be reading >1v.. excessively rich(counter intuitive), or shorted to a power source..

During scanning, does the B1S1 go fully lean (<.02v) when decelerating (foot off gas) from hiway speed?

Have you checked FT's?

.. Philip

I would love to get on the road readings, but alas my daughter takes a DIM view of anyone(family included) driving her car. I even said she drive I ride and monitor the scanner, she said no way as the cable bothers her(afraid it will get wrapped up in the steering wheel). I have about had it with her attitude to be honest and am ready to go buy a princess wand for HER to wave over HER car and magically fix itself.
Yes it is the 4 banger, and terms you are using do not match to terms on my scanner. O2S11 at idle reads roughly .5V, O2S12 reads 1.5V
(roughly) semi warmed up< 5 minutes run time at idle, PARKED. And values fall and rise as the motor runs. I am assuming O2S11 is upstream O2 and O2S12 is downstream. So which one would be dead or lazy, as the downstream sensor is now a month old and upstream is original. Either way tomorrow morning I will check things with scanner again and report. BTW.. what are FT's you are referring to?

FT= fuel trims, short term(STFT) and long term(LTFT)

B1S1=bank 1, sensor1(upstream) should switch between .05<>.9v, as ECU adjusts the FI trim to maintain stoic 14.7:1 fuel/air ratio.
B1S2=bank1, sensor 2(downstream) should be fairly stable ~.45v, conditioned by CAT..

... Philip

BTW: Tell your daughter if she wants you to fix her issues, she has to let you diagnose.. alternatively she has to pay the piper..

Ha Ha, Like I said I have been wracking my brain(?) on this and must have come down with "burn out" Because as soon as I glanced at abreviation of the first one it all came back! Sorry about that. Like I said earlier, I don't get a lot of time to monitor things from daughters attitude. But will pay more attention and record these onto paper in the morning (I'll start at 7:00 EST), she leaves at 8:00. And I totally agree with you on your BTW statement!!!
BTW.. I can snapshot and put on my pc but have yet to have had the need to do it for any of our other 4 cars, so I may be a little delayed in reporting in tomorrow! LOL And Thank you!

Well to the best of my ability,
First off I transposed B1S1 and B1S2 figures as posted from idle readings. and this am these reading on decel on the road B1S1 climbed to 4.5 -5.0 and B1S2 hit 2.0
LTFT was reading 3.9 and STFT was -1.7 during decel
EVAP purge was 0
EVAP monitor test was still incomplete and P0139 and P0139 pending was in computer memory with No CEL

So IF I may assume, the evap solenoid is either not working or I have a bad upstream O2 Sensor(B1S1)
If Evap, why would it not show an EVAP code?
It is raining like crazy here and I am working in the driveway(no garage). I have until 8:00 am EST to try other suggested readings or checks.

Thank you so much for your help!

I shortened the list of "PID" items to monitor (all requested items were not showing without scrolling the display), and found that I was getting EVAP readings and they seemed ok. but I really did not like seeing the B1S1 readings going up to 4.5-5.0 V on decel and B1S2 would hit 2.0V and then show 0 V and then quickly show around .700 to .850 v. I think(?) a wearing out/B1S1(upstream) O2 sensor may be the prime culprit? Yes I did a second run before daughter got around! She was more pleasant this am as the CEL did not come back on for her yesterday as it would do for her long driving days previously, so the spark plugs and seafoam helped some(or maybe tightening the gas cap)?

Again your O2 data does not make sense!

Read the following, o2-sensor-testing

It may clear up some of the misinformation, baring that you will have to verify the O2 response..

We are experiencing the deep freeze here -21*C.. much prefer the rain..

We have just gotten out of those temps! LOL
Those are the voltage numbers from the display of the scanner,maybe scanner I have is reading in a different scale as all values do change and frequently. All my other vehicles have older systems and O2 sensors are three wire unlike this year kia. Maybe that is what may be messing up my thinking process. the Link you sent me is quite informative and I will be rereading and watching the video that is in it until I got it "nailed". Also the car is gone for the day again and won't be available tonight. Thanks again
BTW the scanner is an Actron CP9580A that was given to me minus instruction booklet
