Thread: clear codes

So I went back in and disconnected the battery the following the morning and left it offline for almost 2 hours and came back and rechecked all connections, even the O2 Sensor and then reconnected the Power to the battery and the code was cleared. Hadnt come back since.

Glitch or not? Not sure cause if it was truly a bad sensor it would have kept coming back.

the P0171 is NOT an O2 code. i know it seems like it could be, but it's not, at least according to the trouble code diagnostics from GM that i posted up over on the how-to section. anywhoo, mine was a vac leak, allowing unmetered air into the system after the MAF.
