Can I replace the air/fuel ratio sensor on a 2002 camry XLE myself?
The air/fuel ratio sensor (an O2 sensor) is screwed into your exhaust system and has an electrical lead. They can be tricky to get loose and you can’t use a socket or box end wrench because of the electric lead but still not that difficult to replace. Below is a link to a picture of this part for an earlier model. Though they both have the word ‘air’ in the name, the Mass Air Flow sensor is a different sensor. It measures the amount of air moving into the intake.
