ECM Monitors and drive cycle

Okay I have a question about the drive cycle in my 14 GT as it relates to the 8 readiness monitors.

I recently had a dead battery and had to have it replaced. Then my car was shipped to the great state of California. I'm no virgin to Cali smog (as I have been given the smog fail right in the arse more than once in my life). I knew my car would need to complete the monitors to pass. So I drove the car about 5-6 days about 300 miles.

Took it to a smog shop...fail. 2 readiness monitors not complete. The oxygen sensor and oxygen sensor heat.

So I drove some more. Another 2 days. Plugged up my PLX Kiwi wifi OBD II...still not ready. I noticed I had a stored code, it was an ABS POWER FAILURE. I read on some sites that if there was a stored code it may keep the computer from completing the readiness monitors. So reluctantly I cleared the codes and had to start the refined monitors all over again.

I followed a ford OBD II drive cycle I found online. This got me right back to 6/8 monitors completed in less than 30 min. Still the same 2 were not complete. Keep in mind there was no cold start this day as the car was already driven earlier.

So now I have once again driven the car everyday. I have clocked 2 tanks of gas, ~650 miles over about 5 days. Still monitors mentioned above are a no go.

So seriously what the heck? It should not take this dang long. Has anyone had this issue? Or does anyone here know exactly what the computer is looking for to complete this monitor? My car has no tune, never has. I have never had a check engine light. I currently have no codes pending.

I would try to find someone with a high end scanner like a solus ultra, and have them do a reset of your PCM. Mine does this, but that is so that I can trick the PCM into not triggering a code for catalyst deficiency.

Okayyyyy

Maybe you can explain what the difference is between resetting my PCM with any old scanner and this solus ultra is?

And let's say for giggles I can't find said person with said scanner. (Since I just moved here and know no one here). Then what.

Also, resetting again? Da fuk? I'd sure hate to lose the data I have already logged.

How is any of this going to help me?

I'm interested in knowing what the computer is looking for to complete the readiness monitors I'm missing. I can't find anything that says what it needs to see.

I have read some sites say cold starts with a warm up for 2.5 min then drive at 40-45 mph for 5 min.

Some say cold start and warm up to 180 degrees then drive 40-45 mph for 10 min.

I have read to put the AC on max and defroster on and cold start for a few min then drive.

I have done all of these with no success.

Getting them all ready is hard, really hard. I know this from personal experience.

But don't reset the computer as that will do you no good.

Alright well that makes me feel a little better. Any insight on how to get the oxygen sensor and oxygen sensor heat done?

Try and follow the Ford drive cycle as much as possible. I know I've posted it the past. Some computers are harder than others with the 2014 being the hardest from what I understand.

If it's the two rear cat o2 codes that need to be cleared try accelerating from 40 to 60 very gently, and then letting the speed drop back to 40 without using your brakes. Do this 5 times in successon and see what happens. It will be hard obviously as you'll need a long stretch of road without much traffic. Stick with it and they'll come around eventually. But do not reset the computer.

ECM Monitors

Been having this same problem for 8 months now in Idaho, last two monitors giving me the same headache, I have 07 Shelby GT 500, extensive after market work on the engine, longtube headers or the high flow cats are doing me in, that's what I've been told

So I found a decent farm road to do this 40-60 x5. Did it twice. Once in 5th gear, once in 4th gear. Still incomplete.

I had a weird problem recently.... may or may not help you out.

I was receiving a failing cat code. I think it was P0420.

I was also getting a stumbling idle on cold starts only.

Long story short, turned out to be a dirty MAF.

Yeah, I don't know that this will solve any of my problems. I have zero codes pending and have never had a CEL.

But thanks anyway dude.

Yes I'm having trouble with 0420 and 0430 codes and can't seem to get 3 (not sure which 3 they are) of the monitors up and running. Can't pass inspection as I need no more than 2 of the monitors to be incomplete.

I'm in a similar situation. I can get all the other monitors to run and complete, but I cant get the O2 and Heater to go ready. Everywhere I look for answers people try to help with the cat monitors, but that's not the problem in this case. For some reason the O2 and heaters wont go ready on several 2014 mustangs I've been dealing with.
