You DO NOT go to inspection without either
working on all vehicles or at least use a professional
scanner to see if all 8 monitors have run

If they haven't run or you have a fault code after they run,
you fail inspection

So you get the Evap Codes,diagnose that system & it's components, until you find where a vacuum leak is or what
solenoid failed.

That is best done at a shop with a smoke machine & knowledge

Emission Monitors run on their own every few days

What your referring to is Drive Cycles after certain repairs
have been made

You don't do them either,a shop does before you get the car
back or they are useless & you don't go their,too technical
for you to do & the info has to be looked up

You need a clear piece of roadway with no traffic to to Drive
Cycles

I have a 03 f 150 4.6 2 wheel drive I lost overdrive and reverse at same time no warning and have a code p1000 how do I fix

Code P1000 is nothing , just the codes were cleared or battery was disconnected ,that's all that means . Does the O/D light flash ?
P1000 - OBD (On Board Diagnostic) System Readiness Test Not Complete The OBD monitors are performed during the OBD Drive Cycle. The P1000 will be stored in continuous memory if any of the OBD monitors do not complete their full diagnostic check.
  • Vehicle is new from the factory
  • Battery or PCM had recently been disconnected
  • An OBD monitor failure had occurred before completion of an OBD drive cycle
  • PCM DTCs have recently been cleared with a scan tool
  • PTO circuit is shorted to VPWR or B+ or PTO is on during testing
The Ford P1000, inspection/maintenance (I/M) readiness function is part of the PCM strategy. A battery disconnection or clearing codes using a scan tool results in the various I/M readiness bits being set to a "not-ready" condition. As each non-continuous OBD monitor completes a full diagnostic check, the I/M readiness bit associated with that monitor is set to a "ready" condition. This may take 1 or 2 drive cycles based on whether malfunctions are detected or not. The readiness bits for comprehensive component monitoring, misfire and fuel system monitoring are considered complete once all the non-continuous monitors have been evaluated. Because the EVAP system monitor requires certain ambient conditions to run, special logic can "bypass" the monitor for purpose of clearing the EVAP system I/M readiness bit due to continued presence of these extreme conditions.
Note: The P1000 does not need to be cleared from the PCM except to pass an I/M test.

2002 Hyundai Elantra that says my on board computer is not ready to be tested. Emission results are: readiness- fail, monitor comprehensive- not ready, monitor EVAP not ready,monitor O2 not ready.

Did you recently clear the trouble codes or disconnect the battery? Once all codes are cleared, the computer will not display systems 'ready' until they go through an evaluation cycle. Some of the systems require a certain number of drive cycles before they will display 'ready'. A drive cycle is usually starting the engine from a cold start (based on coolant temperature) and driving until certain conditions are met. I don't know what the requirements are for your car, but my 2003 pickup truck requires more than 10 drive cycles before it will make the O2 sensors and evaporative emissions 'ready'. Most states only require that a certain number of systems are showing 'ready' to pass emissions certification.

Why do i get OBD/READINESS, Not ready?

Alan, I f you have had battery disconnected or had some one erase codes recently, the computer has to go through what is known as a drive cycle to complete all monitors cycling, some vehicles complete cycle in 10 miles, where as some could take 100 miles or more.
My Toyota EVAP readiness state will not cycle in cold weather and takes thousands of miles before it gets to readiness state.
I think some shops can force systems to run if they have a good scan tool.

HAVE A 2010 SUZUKI SX4, CHANGED BATTERY, WENT TO GET INSPECTION, FAILED. MECHANIC SAID I NEED TO DRIVE IT ABOUT 80 MILES TO RESET COMPUTER. WHAT DO YOU THINK?

Is see stress.. i feel it. CAPS
that is correct. removing the battery resets the ECU/PCM
this causes all EPA mandated monitors to RESET TOO.
and you must drive them to completion.

the 2 hards ones are:
EVAP, take must not be full. keep below 3/4 and drive.
(hint, needs that air space on top to run the test)
EVAP mon. can take 30minute so finish on many cars...
(evap means fuel tank vent system tests) EPA is strict here.

EGR. takes, a hot engine. drive fast, say 45+ mph and cruise on flat ground
this finishes, test 1, test 2 is , coast fast to a stop. gently braking.
free way off ramp is perfect stop.

all others are fast on a hot engine, and yes it must get
to 180F+ and hold hot, or all bets off,.... all. !!!


if you had $9 fleabay scan tool
this is what youd see.
see not complete?? bingo.

How many miles do i need to drive before my buick lesabre reset itself

Unfortunately it is not a certain amount of time or miles that the car needs to be driven.

There are several 'readiness monitors' that basically cover each emissions related system. For instance there is an EVAP monitor that checks the EVAP system and all of it's components under certain specific conditions (No VSS, TPS, O2 sensor, IAT, MAP, Fuel trim, Injector ciruit, EGR pintle position, ECT, or MAF sensor DTC codes set; Start up engine temp 40F-86F; gas tank between 15% and 85% full, Barometer above 75 kPa, system voltage 8V-16V).

So more information is needed as to what failed you the first time. What DTC code was triggered?

If the problem has been fixed right, the history codes will go away after 40 CONSECUTIVE drive cycles WITHOUT the problem re-occurring.

Good Luck.

I have a problem with my 2001 Toyota sienna, took it to inspection yesterday to get inspected and didn't pass results Cat not ready and evap not ready, inspector tell us run the car couple miles and bring...

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.

Monitors not ready: Catalyst,Evap System, Oxygen Sensor, Egr Syst

Drive it some more. Has the battery been disconnected/replaced recently? The Inspection station should be able to print you out a drive cycle to get the monitors ready also.
