It is driving cycles not miles. It varies from manufacture to manufacture.
Takes about 50 miles highway and city combined.
50 to 100 miles
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.
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
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.
Try removing negative battery cable for 10 minutes. If that does not work you will need an OBD2 scan tool to reset the light. I just cleaned my egr valve and the check engine light went off and I drove it a little and it came back on how long do I have to drive my car after work with the egr valve how many miles
Auto Zone or Advanced auto parts can reset the light for you. They tell you they are not suppose to but many times they will.
There are many reasons for that check engine light. You could go to dealership. Or you could simply disconnect battery and reconnect after 3 minutes.
disconnect battery for 10 minutes then reconnect battery this will cancel error codes in computer
50 miles
It is safe to drive you car for at least one mile after the check engine light comes on.
As on all cars, you need an ECM scanning tool to reset the stored codes in the computer to turn off the check engine light. Many auto part stores will do this for free.
