How long does it take O2 sensors to show ready?
- Thread starter Katy TX5.0
- Start date
I run my Emission Monitor test on my to work and back home. Usually takes me about 66 miles to complete everything.
First 22 mile trip to work. I drive 70mph normally on the freeway.
Second 22 miles heading home. I drive the feeder road hitting traffic and lights.
Third 22 miles, I set the cruise control to 60mph and drive to work, all freeway.

Do you have cats or no cats with your LTs? I couldn't remember. If no cats, they didn't do a visual?
He has triple checked, he even sent me a revised tune. From what I have read and what he told me some computers are just stubborn and take awhile to go ready. I was curious if anyone else had this issue. I don't want to give up on it yet but my patients are wearing thin. I did almost 500 miles on my first emissions tune so I'm over a 1,000 miles into this process. Thanks for your feedback.
No cats. It "passed" visual.;-)
Shoot me a pm where u went. I need a visual friendly place so I don't need to swap my stocker every year.

I am having the same issue. I have kooks lt headers with high flow cats. I called Bama to get a emissions tune, and put that on. I also have the non foulers. My car has never thrown a CEL because of the O2 sensors, but it reads: Catalyst...Not ready, Oxygen sensor...not ready, Oxygen sensor heater...not ready. I cannot figure out how to get everything ready. Any help would be greatly appreciated.
My whole Emission Statuses were ready in 66 miles.
It is mixed driving, not just all highway.
I use Torque on my S4 phone to see the monitor statuses.
Make sure he has added the emissions part to your tune. Otherwise the rear 02's are off and you will never pass inspection.
Is the sct handheld capable of monitoring o2 readiness?
I believe it will as long as you use LiveLink with it.
I don't think the handheld will do it by itself.

No. SCT tuner will not run the Readiness test from what I have seen. I gave in and got a OBD reader that tests for readiness.

I used the livelink software, but was unable to determine how to run a readiness test. I saw the options for the oxygen sensor, heater and all, but couldn't get it to work.
I'm part of this club now too. I was running a bama 91r with an orx pipe. I knew this wasn't going to pass, so I swapped the stock cats back in and loaded a bama 91s tune. Drove it around like that for 250 miles or so and it still wouldn't set the o2 and o2 heater monitors. I figured it may have been an issue with the tune, so I loaded the stock tune back and have since put another few hundred miles on the car. The rear o2 sensors are turned on and I get all the other monitors to set pretty quickly.
The rear sensors are functioning just fine looking at the voltage on my scan tool. The catalyst monitor resets just fine too. Would an issue with the sct templates or software still affect the car after returning it back to stock?
The only other thing I can think of is maybe the 3" xpipe is throwing the readings off just enough to not set these final two monitors...
I just swapped the stock 2.25" h-pipe back and will drive it around some more in the mean time.
Are the new AED 'emissions tunes' a solution to this issue? If so, sign me up!

Here's some reading material on the ford obd2 system. All the different systems and monitors are explained in detail.

How does it not turn on a CEL when you have no cats and the rear O2's turned on? Mine will turn on the CEL with high flow cats.
You Houston guys know if you head out to Waller they don't do emissions testing right? And it's only 15 bucks.
Do I need the update if I got the emissions update back in October?
Possibly, I would have to check your tune file.
Email me as a reminder and I will check later this afternoon when I get back to the shop.
Will do :beer:
Can they just do a safety inspection for a car that's registerd in an emission county?
Hey guys the note 3 is bad as ****
