ECM actually recalibrates when you change TPS based on the high and low voltages the new one shows, i.e., it does not expect an EXACT match, just close................I get a high % (actually around 19 or so just like yours!) on my scanner too, but in my case it means nothing since both cars run perfect. When I first saw that I thought about it, but time has rendered the point moot. Check the voltage range with VOM and compare to the average numbers given as acceptable. Voltage more important than % since every device can interpret % differently.
