Two ways to reset the computer. I recommend the first as it requires no tools or effort on your part other then driving.

1) Go to autozone, advance, oReilly, Napa, etc. Get them to put the ODB-II reader on your port and a) get the codes and b) wipe the codes. No charge.

2) Disconnect the + pos cable from the battery for about 1 minute. This allows the PCM to reset.

 

see i got it cleared and replaced the o2 sensor and its still registering not ready on all 3 of those deals
