Lexus: Help Throttle Position Sensor RX300

Hi,
I finally found out why my check engine light is on. The throttle position
sensor is causing it. Can anyone tell me where this sensor is and if it is
difficult to replace myself?
Thanks

I'm not sure of where it is on a RX-300 but it is on the LS-400 I do. Pull the
top cover over the intake . It will be on the front side of the air intake just
before the air goes into the top of the intake header. It will be a black
rounded at one end and a plug in for atleast 6 to 8 wire to plug into it. There
will be 2 screws holding it on there and they are hell to unscrew and you need
a 2" screw driver to get to them.

Well here is one for you. Go down to Auto Zone and have then look up the TPS for
your year and model and they will show you a pictuire of it and have them show
you on your RX where it is. They will go out side and put their finger on it for
you. The TPS for the LS-400 cost $99.00 at Auto Zone and Lexus wants $140.00+
for them.

Now the TPS is the same exact switch that goes on most all the Maxima Cars also.
The replacement at Auto Zone has Toyota wrote on the top of it.

It is simple to change but you got to fool with those two horses behind of
screws holding it on.
