  1. Hey

    How can I reset my check engine light on my 96 mustang? I replaced the O2 sensor that was bad but even though I disconnected the batter for a few minutes it still hasnt gone away.. have I just not left the battery disconnected long enough?
  2. try leaving it unhooked for 30min. :nice:
  3. :stupid: if that don't work, do it for overnight
  4. OK, thanks I am in for the night anyway so I jusrt unhooked it and will go back in the morning should be good and clear then
  5. A few minutes is more than enough to clear the code. If it's still on there is still a problem. Make sure you have reconnected the connector (just in case) and check all other connectors under the hood. If you have a scanner, check the codes again.
  6. Yep.. unplug battery, open door to discharge power in capacitors, reconnect. 3-4 minutes is probably even more than enough.

    Before I bought my code reader, I had autozone do it for free.
