This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

SOURCE: engine revs itself when sat idle
bet it failed on lambda reading...........sounds like you got an air leak somewhere ! or could be an idle control valve problem,have you had it plugged into any diagnostic equipment yet ?

THERE IS A TEMPERATURE SENSOR ON MOTOR WHICH CAUSES THIS PROBLEM... USUALLY IT SHOWS A NEGATIVE TEMP READING WHICH CONFUSES THE COMPUTER CAUSING IT TO REV UP....HAVE THE ENGINE DIAGNOSED ON A SCANNER....GOOD LUCK...

Rough idle can be caused by dirt in throttle body or EGR system, but there are many other possibilities. The service engine light indicates the computer has detected a fault. If you can get a free scan at your local parts chain and post the trouble codes to us we can give you more specific repair recommendations.
