Okay i noticed in the day when it is like 85 degrees out, my cel turns on almost immediately and i get code 17. At night when its around 50 degrees out, it turns on after 15 minutes or sometimes not at all. What could be causing this!? Its my only cel left to keep the light off. Thanks, Jim

 

code 17 is speed sensor dawg... it just happens... replace it and reset the ECU...
