Dies the throttle body come with the sensor?A shopperNov 14, 2020
Best Answer:Hi, Upon checking, the throttle position sensor is sold separately. To look for the correct part, please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

Throttle Body, 8/6 Cyl., 5.3/4.3/4.8/6.0L Engine
Don't buy cheap Amazon junk these are good
Bought two separate throttle bodies off of Amazon roughly 50 $60 both of them would not idle properly and rattled inside fresh out the box? Finally ended up purchasing this one put it on the blade was already preset at 7° fired right up! Running great ever since
