Hello, Sometimes you have to drive 20, 30 minutes or more before the computer loses the code and resets unless you still have a problem
I hope this was helpful.

Replaced battery and BCM (reprogramed by dealer)and cleared ECM trouble codes. OBD wont acheive readiness for emissions testing even after 600+ miles. Can anything be done to complete readiness?

motor itself
the 02 sensors
the catalytic converter or the
engine emissions /gas .. filtering /re burn system

03 focus engines sensors not ready for emission test but not reset manually or battery disconnect

You need a professional scan tool & road test, to
gather data, to find out why some of the 8 Emission
Monitors won't run

Have to do that before you go to inspection, every time

If you fail to check I/M or look at data or do Preventative
Maintenance, your going to fail, possibly

You said nothing was done

That is your answer

You can not just drive a vehicle & not
work on it, several times a year, or know
what the data looks like, or if codes are in
the systems

There is no reset & you do not remove a battery cable

If you remove power,you just clear all memory & info,
you need to diagnose the vehicle & then the Monitors
have to run again

You could loose a few days before they run again by
doing that

If monitors do not run clear, then your statement about
no running issues, is not true & you could be ruining
your exhaust converter

Obd computer won't reset

you can force the engine light to come on with ready or not software (type it in on google) i have this gear. your ecu has to reconise all emmissions sensors data on a 3times in a row before it will complete a full diagnostics cycle.
the ready or not scanner and software will atomatically do everything for you and tell you when everything is ready (so much easier than messing about guessing all the time).
you can also program scanner to your state regulations aswell.think it's about $50 now

hope this helps.

Emmissions test can't be finished because the computer needs to be reset after a new battery cable

That should be enough time to reset the emission systems. Did you clear codes since then or remove the battery or one its cables for another reason?
Check to make sure all the battery cables are tight and clean. Sometimes if a cable doesn't have a good connection to the battery due to being loose or dirty, it may not allow the battery to keep the car's memory when it's shut off so may reset the emissions.

I have an 04 cavalier. Code P0172 mechanic changed upstream 02 senor. light came back on. Brought back to mechanic he changed the downstream, light came back on. I changed fuel filter, spark plugs, oil...

Think your guy changed O2 Sensors ,
but didn't consider that your sensors PO172
is rich,because it is correcting for a lean condition

I'am going to really guess here

The EVAP has leaks,but no codes set,
partially driving the system lean (Vacuum Leaks)

The Converter is sort of out there as
not working well either

I would smoke the EVAP System and everything else,
intake manifold etc

I think you will find this by MAYBE even just looking
for a bad hose leak

Is that data from your mechanics scanner ?
What is their theory ?

Bank 1 has a vacuum leak I think !! ??

Po 440 code check engen

p0440 is an evaporitive emission system system large leak detected generally on an 02 gm vehicle it is very common that the vent solenoid located by the fuel tank if you replace it the light will take a few days to clear its self. the vehicle runs tests on all sensors and systems and the test has to pass or fail a number of times before the pcm will turn on or turn off a check engine light.

Emissions test comes up not ready - can't pass inspection

Under the hood, there is a fuse block. I believe it is on the driver's side of your vehicle. Open that box, and pull the "ECU" fuse. Leave the fuse out for at least 5 minutes. Put the fuse back in, start the car, and let it idle for at least another 5 minutes. Do not drive the car, touch the gas, or even look at the gas pedal for these 5 minutes, as the ECU is remapping itself. This will properly reset the ecu and clear the codes. After this you may drive the car.
