Hey there,
I have a 2002 RSX auto transmission.
I recently have experienced problems when the cold weather rolled in. In the morning hours, when I first start driving, about 10 min into the drive the check engine light comes on and the transsmission starts to mess up. It is drivable, but a pain in the ass. To make a long story short I found out that the trouble codes are P0122 and P1298. I have been told by a trusted mechanic it is most likely the throttle position sensor. Acura only sells throttle body, with the sensor attached, not individually. I was wondering if it's possible to change just the sensor? If so, where would I go about getting one, because there is none on the internet that I could find.

Lastly, where is the throttle body located? Maybe I can clean this sensor or something.

Please let me know if you have any advise.
Thanks
