will the SES light reset just by disconnecting the neg battery cable for 15-20mins? i had to change my 02 sensor and i pulled the neg cable for like 30mins but the light still came on when i re started, only had it running for maybe 2-3mins to pull it off the ramps but the light was still on as soon as i started the car. do i need to drive it for a bit for it to go out or...? thought usually the neg cable did the trick??
