2012 Kia Sorento LX 2.4L (1) 6-spd (A6LF2) — 5XYKU3A61CG256115
O2 Sensor Not Ready

Well...... Here we have yet another monitor readiness issue. Unlike most of the vehicles sent to me with readiness issues, this one has not had any repair, no MIL has been on and no low battery issues reported. The customer said the check engine light has never been on.

This is the vehicles first smog test. It failed at another facility and then here with me. As you can see in the file, the light was last cleared 52047 KM ago. 

The In Use Performance tracking show that the O2 is meeting the criteria and completing the test, just no readiness is set. The mode 6 results shown are well below the maximum (if they can believed) I paid the $19.00 for 72 hours of Kia factory service information and did not find anything that shows this is an ongoing issue. 

Obviously, more driving is not going to cure this one...... I don't think new O2 sensors will do anything. I am considering flashing the PCM and starting over... but I hope Randy B is lurking out there and will talk me down off that ledge, or push me off ;-)

Thoughts?????

Its going to be a reflash. Had an issue with one a while back. Flashed it and called it a day. We had another with a 2.4 where we did a battery reset and did the cycle. All was well. I would do that first before busting out the j2534.

Just something to consider, I have had several of these over time where I got the O2 monitor to complete simply by taking it out and doing several WOT runs in a row. It was usually when I got to the point that you are at and figured I had nothing to lose so I took it out and drove it like I stole it. Monitor complete and passed.

Unless California is different you are allowed to have 1 incomplete monitor and still pass emissions.

EVAP is the only monitor that can be incomplete on 2000 and newer vehicles.

That must be a stupid California law​.​In Pa it does not matter which one is in complete.I almost never go the monitor setting route any more​.​Just waiver it.

Not stupid, evap monitors commonly do not run when the temp is really low, so for 3-6 months in the mountainous part of the state(cold part of country) evap is exempted because it may not run for months on many models. Don't you folks in coldsville see a uptick in evap codes in the spring? I'm not saying we have no stupid laws....but this isn't law anyway the process was formulated after 45…

That I know its CAL. I am bashing they are EPA nuts it just different here in PA​.​Some times a clear all and try to hit the parameters will do it.I have seen the throttle snaps work sometimes and check for updates like was mentioned​.​If you use the KDS it will sometimes give you a fault trace.

Some states don't allow any incomplete monitors. Even EVAP. I hear from my relatives safety inspection in PA is pretty rough. In MO it's a joke.

At some point the monitor got reset, even if the mileage doesn't show it. I'm not totally sure if a dead/weak battery will reset that mileage indicator. I believe it would only reset if a code clear was commanded by a scanner. FWIW, I would disconnect battery, touch the cables together and drive it to see what happens. FYI, there appears to be an open recall on that car that would only show up…

Have you ever tried this trick ? "Another good tip for hard-to-run monitors on some vehicles is to force a DTC, then erase the DTC and perform the generic drive-cycle." by G. Jerry Truglia searchautoparts​.​com/motorage/maint…

Back on track, perhaps the chrysler drive cycle will help. I have had good luck with it on Hyundai, Mitsubishi, and Kia. They and Chrysler used to sleep together. here is the link to it courtesy of Rick Escalambre. rlescalambre​.​com/01-Chrysler​.​ht…

We've had many issues with Hyundai and Kia not running fuel system monitor. If car gets to temp and all PIDs look good we generally hit the local freeway and set the cruise control to 52 mph. Monitors will usually set.

I really think this has something to do with the O2 sensor temp. For some reason it is just not getting hot enough for a good response time. As I mentioned in my earlier reply, I have gotten these stubborn monitors to run by doing several WOT runs in a row and then a little cruise. I think it's just fully waking up the sensor. Driving it on the freeway is probably accomplishing the same think…

Well, I did try some of the suggestions. still no luck. Multiple wide open throttles, followed by deceleration. Heating up O2 sensors, inducing an O2 code, then duplicated the condition 3 times and the code cleared itself. I am now going to try and flash the PCM. If the software does not have any updates available, can I flash over it? I can’t remember if that is possible on a Kia? Does anyone…

Hi Jamey: The last one that I had, with a current calibration, gave an error code. Of course, that error message could be for just about anything. Guido

I didn't see the CALID and CVN in your data and the secondary o2 in mode $09 in use performance tracking is also not there. However, check your CALID. The last one we had with CALID XCC4MB3E would not complete O2 after repairs and 357 miles (it was actually incomplete before repairs and a dtc clear was done then). It was flashed to XCC4MB3N and completed in under 19 miles on first drive cycle…

None of the tools I connect show sensor 2. Just bank 2, which it doesn’t have. here are my cal numbers.

That's the immobilizer version of the same engine family as the one I posted and there is a XCC4RB3M available so start with that. A "M" for you is the same as an "N" for ours (2wd vs. 4wd). HTH.

Well.... for some reason I was not able to get the KIA server to connect, while I was doing that, the customer received an email from KIA about a recall that involves a flash! So off to the dealer he goes. He will return after the flash to see if the monitor runs. I will post an update when he does. Thanks for all the replies.

Any idea what recall notice he got? There is currently no reflash for your particular concern.

I do not know at this time, When he returns, I will see if he has the invoice. I went on the Kia web site and I did not find any recall related to monitors. Stay tuned......

Ok, the customer called me today. KIA did the flash for them at no charge. They told them the flash has nothing to do with monitor readiness. His wife took the vehicle to the original shop where it failed. (They had a free retest) and it passed after just 2 days of driving around. All monitors ready. I told him I knew there wasn’t a flash specifically addressing this issue, but my hypothesis…

Had the same problem come in from another shop. All monitors had completed except O2 sensor. The customer had driven the car over 300 miles. The other shop reset the monitors and started over and same problem. I noticed the long trim fuel trim was a little high. I reset the engine control module adaptation and drove around the block. The adaptation reset did not reset the monitors and the O2…

Abraham! You Da Man! I had a 2012 Kia Sorento come in with the O2 Sensor Readiness Indicator Incomplete. You can see that from the clear code that the vehicle had traveled 12531.19 miles. The calibration was XCC4MB3K and there was the XCC4RB3O available. I was ready to flash the consumer's PCM, but when I read your post, I thought, why not give it a shot. The fuel trims didn't appear to me to be…

Danny, We have also verified the same but there is an issue with these running rich before resetting fuel trims and the condition appears to return after driving. Was your fuel trim positive and how much? Did you check 4 gas readings began after clearing? Thanks. Edit: I see your fuel trim now. 11.5% total. Along the same lines we see. Was it running slightly rich?

Randy, I didn't check the tail pipe gases before clearing the adaptives. The consumer returned yesterday after driving the vehicle about 50 miles. I took some screenshots from my scanner. Autel graphing is difficult to adjust the scaling. I also took some tail pipe measurements at 15 and 25 mph with the dyno set at BAR ASM values. Edit: The consumer had felt that I did enough to get her car…

Thanks. Don't forget about PIDs 55 and 56. Did you notice the VVT mode $06 reset values to 0? Resetting the adaptives does some weird stuff in the software. One of our tech centers tried this method to see what would happen and it reset miles since DTC clear to 0 and did not reset warm ups. Most all of them have had a high PID 56 value. I had a similar Hyundai, same year, with a P2096 set and…

Jamey. I know you have lots of experience and you have probably done this already. It sounds like a reflash may be the answer, but it is worth trying a 10 second decell after 5 minutes at 57mph, repeated 2 times. Kia, Hyundai, and Mitsubishi all seem to respond to this protocol for me for O2 monitor. Good luck.

Hi Mark. Thanks for the tip. This vehicle is long gone. I posted this 9 months ago. Someone just recently replied and it got refreshed. I did run several coast downs after cruise on the dyno. This vehicle ran the O2 quickly after the Flash. Thanks Jamey
