I own a 97 Diamante that has set a P0120 Code indicating a failed throttle position sensor. Before I spend the money for a replacement (>$100 USD), I would like to confirm the failure. Is there an way to read the voltage at the sensor? If so between what wires? Between what values would the sensor be set as idle?

I have been to two bookstores and two autoparts places and they do not have either Chiltons or Hayes in stock,

my E-mail is artsemail@comcast.net.

Thanks for the help
