How many miles does it take to reset drive cycle

You are simply driving it. A drive cycle will reset all monitors in minutes. Do a google search for your year make model car and read and follow instructions to the T or it will not work.

you have to drive at least 125 miles to reset and cycle computer some try the drive cycles they dont always work but the following links show you how to perform them

Drive Cycle and Emissions Readiness Monitors

Cars do have a drive cycle to clear up a fault. It more less ensures the issue has been corrected after a certain drive cycle. Some issues have to cycled for 500 miles.

It's not a matter of miles, but the number of drive cycles. Each drive cycle includes low and high speed driving, and I think there are 10 drive cycles required.

"drive it around more" is the solution. This allows the ECU to "learn" and store the operating conditions for emissions. 100km/ 60 miles is usually enough.

This means you must drive the car long enough for all of the self-tests to run. Depending on the test it could be a single start and run to many cycles and many miles. Usually after about 50 miles of driving you have completed most tests.
I'm not sure where you are located, but in Ohio you can ask and have the car run on the dynamometer and compete your smog test this way.

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.....

Drive cycle has to do with normal everyday type of driving. So many stops, so many miles, fast driving, slow driving. My car went thru a drive cycle in about 38 miles on my way to work. My daughters took 3 days and about 78 miles. So just drive it like normal.

it requires what is called a "drive cycle" , just a one hour drive around highways and city at different speeds will more than safice........good luck, marty
