      This will not FIX anything. All it does is reset the adaptive values for a little while and resets the modules until the conditions are met for the DTC to flag again. This will also stop a vehicle from passing an emissions test. A bad bandaid at best, but not fixing anything.

    Works every time. You have to turn the lights (or any electrical item) on to completely drain the capacitors (work very similar to batteries) in the computer (ECM).
    Another fast way to drain them is to short circuit them by touching terminal you took off to the other terminal. This is the same as using a screw driver across both leads or a capacitor. This will NOT cause a short across the battery if all wires are off either side of the battery.

    I had a Nissan where if you disconnected the battery a service warning light would come on afterward (in this case, during a new battery install). The only way to remove the warning is go to the dealer pay them $150.00 to reset / turn off the light or I imagine you could purchase an inexpensive OBDC diagnostic tool to reset it yourself but how to know which of those tool level's you need to have the ability to reset that particular fault I do not know. I do know not all OBDC have the same capability and or ability to reset specific issues.

      Has nothing to do with miles. Each mfr has a different set of complex parameters to pass called a drive cycle. Viewed in detail they appear almost impossible to quickly target, in average takes about 2-3 weeks of operation. Cycle your HVAC system frequently, can assist as well as driving in a variety of conditions, freeway, city, etc. Hondas drive cycle includes decelrating from 50 mph to 0 without applying brakes. Is this even possible?

    Also, there are reasons NOT to do this...so be sure you research and understand the benefits and pitfalls of doing this. You should put a code reader on first to find out what codes are present. After 1 to 50 miles of driving, those codes (or check engine light) may come back.

In many cases codes can be triggered because of another problem. A cam timing or phasing problem will absolutely affect airflow parameters into the engine and the code is the computers reaction to that. I bet your timing is off, or the actuator controlling timing is plugged or broken and it's stuck in one direction.
