Unable to reset a code
I just finished changing out an O2 sensor and since I don't have an ObdII code scanner, I tried disconnecting the battery cables and waiting 5 mins at least to clear the code.
The "service engine" light is still on....Did I do something wrong or is there a better solution without needing the scanner?Matt

Mike, I've never heard of doing that...I was going to leave them disconnected for a few hours, but then just went to the store and bought a 50 dollar ObdII scanner and was able to erase the code. I let the truck run and no check engine light so all is good right now.

Uh, I hope Mike was kidding as I have never heard of that and know that that's pretty freakin' dangerous. Only way I have been able to delete codes is to use a scanner.2005 Chevy Silverado W/T

Never heard of that as well Mike. Some codes you need a scanner to clear while others you can disconect the cables. Sometimes if you don't have a scanner or access to one you can replace the part and depending one the code most will clear themselves after a certain amout of drive cycles.
