This will vary depending on the vehicle. Some may require a certain number of ignition cycles. Others may require a certain number of miles (eg: 20 miles). The course of driving over a week should satisfy the requirements.
The light won't reset until the problem is fixed.
With my 2000 Blazer it is 100 miles. I've been passing emissions by clearing codes for 6 years driving off the miles and passing.
65 miles
After you have fixed the issue that caused your check engine light to come on, you can use a pocket scanner to erase the code, but this causes your computer to reset and during an inspection will cause many unready codes failing the inspection. You must drive your bravada 5 miles at a non-stop 55miles an hour to clear the computer, sometimes it just takes a few days of driving to get the reset to clear all codes but normally the 5 miles at 55mph will do the trick.
It is driving cycles not miles. It varies from manufacture to manufacture.
First of all It's spelled "ODOMETER" and it tells you the overall miles your car has and also has a second reading that tells you how many miles you've driven since you last reset you "trip." It won't reset the overall miles of your car but it will reset the recent miles you've driven. I always reset my trip meter every time I fill up on gas so I can see how many miles I got out of my full tank.
disconnect battery for 10 minutes then reconnect battery this will cancel error codes in computer
58 miles
5 to 6 miles at the most.
About 50 miles , however it can be as much as 250 This is to prevent you from resetting the ECU to pass an inspection , these miles will allow the sensors to reset and detect a problem.
you need to drive between 40 ti 50 miles to pass emission test , if the light comes back before that , you need to fix your car
Takes about 50 miles highway and city combined.
