What is a reasonable cost to replace the throttle body and reprogram it?
you shood not have reprogram computer just clear codes
The throttle body HAD to be replaced with new one.
There is an updated recalibration for DTC codes P2106 and P2135 that is designed to improve the computers ability to process the throttle position signal. Unfortunately, I see this component mistakenly replaced many times. If there are any misfire or MAF/ baro codes, this could be caused by RFI or radio frequency interference. Like your AM radio making static noise near an electrical transformer, a component such as a failed ignition coil could be producing an erroneous code using RFI. These concerns are a trick bag, so be sure to tackle all other codes before chasing down the throttle body. To answer your original question, the repair costs to replace the throttle body would be around $350-$500 dollars.
