Hello and welcome to justanswer.com
That code 17 is for the throttle position sensor located on the bottom of the throttle body. This code is caused 99% of the time caused by a bad sensor. Here's how to test it. Go to the sensor connector and make sure you have 5 volts on pin 2 pink/purple and a ground on pin 1 black/yellow. Then go to pin 3 green/yellow and you should read about .80 volts and it should increase to about 4.90 volts. Make sure the signal does not drop out.
