It's called a drive cycle, and yes, there are certain parameters that the ECU stores for calibration. In many states that require yearly vehicle inspections, they will make sure a drive cycle has been completed before passing inspection, just to make sure that someone hasn't cleared the codes to get the check engine light to shut off to pass inspection. A simple trip that includes some highway speeds and start & stop driving is usually sufficient to complete a drive cycle.
All in the link, but this is it. Also good to use a bottle of Fuel System Cleaner
I wanted to post this on here because a Ford technician was nice enough to give me this information. Here is what needs to be done to load all the parameters in your computer so your vehicle will pass inspection after your check engine light problem has been fixed. This will work for all explorers 1996 and up. Here is what you do. This will save you from having to drive 3 or 4 hundred miles to load the computer.....
1. The gas has to be between 1/4 and 3/4 full. Not above or below.
2. Start the vehicle and put it in drive and hold the brake.
3. Turn on the air conditioner and the rear defroster.
4. Sit in drive for 2 minutes.
5. Turn off AC and rear defroster.
6. Drive the vehicle up to 55 mph.
7. Decelerate down to 20 MPH, do not touch the gas or the brake.
8. You must do this 3 times and let the vehicle get cold between cycles.
I did this today and my vehicle passed inspection. I hope this helps others that need to get their rigs inspected and don't want to drive around for a couple hundred miles.....
You still fail your state inspection if you turn off the check engine light. So Im sorry to say, that your gonna have to wait untill your new cat gets installed. After its installed you have a few options for turning off the check engine light. -You can disconnect your battery for a little bit. -You can take it to pretty much any mainstream auto parts store and they will clear it for free. Either way you have to complete what is called "a drive cycle" to be able to pass your vehicle inspection.
DRIVE CYCLE Once problem is fix you complete a drive cycle. Every vehicle is different so this is a general guide. -There are a certain number of times your vehicle has to be started. -There is a certain amount of time you have to be driving at different speeds -There are sometimes a certain millage that has to be reached (ie. drive 75 miles) If you just drive as you normally do for 100miles (not in one trip) your sure to have reset all the sensers that the state inspection equipment check.
SO IN SHORT Get the new catyletic convertor installed Get you 'check engine light' cleared for free at an auto parts store Drive your car normally for about 100 miles Get your vehicle state inspection
Drive cycles vary by manufacturer. It can be as simple as driving at highways speeds for a certainnumberof miles, or it can bea number of times the vehicle is started and warmed up, then turned off to cool down. A new car dealership service department may be able to tell you what the drive cycle is for your particular vehicle. Anytime you clear the computer on your vehicle, either by using a scanner, or removing power from the computer, you must go through the designated number of drive cycles to reset the computer diagnostics. It's a lousy system, and the auto industry should be required to conform to some kind ofstandard for all vehicles, regardless of make and model. But, for now, it's not clear exactly what you need to do to achieve the required drive cycles. If your inspection has expired, keep the documents you received when your vehicle failed the last test, just in case you get pulled over by the police.
You have to drive the vehicle after the codes have been reset to let the monitors do their tests....If every test ok it will pass inspection....Its usually about 75 miles.....
