How do you reset the computer on a 1990 Ford F-250?

Answer 1

AnswerBy having the problem that caused the computer to set a code repaired. You can remove the battery terminals for 5 minutes and this will reset the light. If it comes back on, have it repaired. AnswerJust telling someone to fix the problem that caused the lite to lite is not enuff. I spun a bearing and lost a motor, and the check engine lite came on, and it is still on after replacing the motor. All connections were made and all sensors are still as they were pre blowing, so a better answer like "Pay a Shop the $ to hook up to a scanner and clear the codes, as long as the triggering problem has been repaired " might be a better choice.
