Check Engine Light AGAIN....HELP

[jmelong]

My 2001 Tundra Check Engine light came on and Toyota replaced the O2 Sensor last February. I later found out that there is a problem with the O2 sensors, and Toyota reimbursed me for the repair. Now the Check Engine light is on AGAIN. Is there any way to check and read the codes without taking the truck to Toyota? How about resetting the light? Any ideas?????

Auto-Zone (and others) can read the code.

- battery terminal disconnect for 30 seconds will reset code.

Not going to work on an 01 Tundra. That trick only works on OBD-I cars. 1996 and later model years are OBD-II. There is no paper clip trick for these. You can take the truck to autozone like a previous post said. They are usually pretty nice there and they will pull the codes for free. If the scan tool just pulls a code they can look up in the computer what it means.

Thanks everyone for the replies and advice. I reset the lite, but it came back on after five miles of driving. I took the Tundra to Toyota, and believe it or not, the same O2 sensor has failed again. Toyota says there is such a high failure rate on these sensors that getting replacement parts is taking 4-5 weeks. On the bright side, at least the truck runs ok for now, and they are replacing it FREEEEEEEEEEEE.
