QUESTION: Thank you! You were very helpful. I replaced it and erased the code. I checked around and the best price I could find was $203.00. Is that right? Thanks again.

Answer
Yes, that's about right,I would recommend using an OEM form the toyota dealer, beware of some of the more inexpensive brands they may not have the electrical connector and the wires will have to be soldered on, the OEM is a plug in installation and may cost a few dollars more but may be worth it and you also get a full one year warranty coverage.
