O2 sensor is easily changed. You need to know what bank and wether its the upstream or downstream one. There are 4 of them. Also, in rare cases, it can be the wiring or ECM. 99.9% of the time it's just the sensor. The code that came up will give you the details of which sensor is faulty.

A new OEM one I think is around $120, there are also some aftermarket ones available for less.

Agreed. You can just call into Carson or Lexus Westminster to get the CL discount and they will ship it out to you.
