How do you fix an oxygen sensor?
Unfortunately there is no fixing an O2 sensor. If the "check engine" light is on due to an O2 sensor, it can only be remedied by replacing the bad sensor.
Can anybody tell me how to fix a p0135 trouble code on a 2002 explorer if i already changed the sensor?

The computer has recognized a failure in this ciricuit. Probable Causes 1. -Oxygen sensor defective 2. -Poor connection at oxygen sensor 3. -Check circuit-fuse
