Trottle body sensor?

I have an 88" Jeep wagoneer 4.0l, and i think the throttle body sensor is going because it will idle high when i slow down to stop and sometimes it will jump up to 2500rpm's when i put it in park. If someone could tell me where at in the throttle body this sensor is that would help. Thanx Jimmy

the throttle position sensor is on the front right side of the throttle body. the front left side is the IAC.

the tps needs to be adjusted to specs so you will need a volt meter.
