I have a coworker that drives a 07 Cobalt LS and her check engine light came on so she took it to a mechanic shop and they told here that her Throttle Position Sensor was out. They also told her that she would have to have it calibrated by a dealership. Is this true? she is tight on money and really doesnt want to take it to a dealer. Thank you for your help in advanced

 

need to replace entire throttle body assembly and have it set up with a tech2 at the dealer
