OK, the code was a o2 sensor, so I looked under the truck and sure enough the o2 sensor had come unplugged. I plugged it back but now how do I reset the codes? I unplugged the battery for ~1 hour and the CEL did not come on right away but then about 1/4 mile down the road it came on again. <img src="/forums/images/graemlins/frown.gif" alt="" />

Driving to autozone every time this CEL comes on while trying to fix the problem would get annoying. Is there a way to flash the codes on the dash without a $$$ code reader? Thx!
