never tried it but heard you can diconnect the battery cables and hold them together for 30 seconds... resets the computer... otherwise sometimes you can get the autozon guy to erase it... just tell them you need your codes checked and when it pulls it up say "i just replaced it, can you clear it and see if i stays away" act stupid... otherwise a shop will charge you $35...

i think auto zone will do it for free, i bought a code reader that clears codes from harbor frieght for like 40 bucks and works well

the batt cables will do the trick. some people say leave them overnight, others say 15 mins. i left mines taped together for about 10 mins and it had cleared the codes and the CEL was off.

most advance auto's/autozone's have code scanners, some will just give it to you to use out in the parking lot to clear the codes.

If you don't live close to an Autozone or Advanced Auto Parts just disconnect the battery for a minimum of 15.

If you pull the batter cables the computer has to relearn which might not be that bad, but also pull the fuse to the radio if it has a memory the voltage from the radio can keep the PCM alive

dicconecting the cables is not an option.
the check engine sign will apear again. you have to scan it
