> My 2016 Canyon lost power and the Throttle Body Sensor code said it was bad. It was replaced, but after driving 150 miles it repeated the error code. Any ideas if these sensors should be replaced in the off chance they are defective? The dealer has had it a week now and isn’t too concerned about fixing it after giving them $500 to do so. Any ideas?

If your Vibe is configured similar to that car above (GMC Canyon I think), the sensor is part of the throttle body and cannot be replaced independently. In any event most likely there’s a sensor in the throttle body that connects to the ecm, which allows the ecm to determine the throttle valve angle (how much it is opened), say from 0% to 100%. Since replacing the throttle body didn’t do the trick, next step, somehow your shop has to be able to compare the actual throttle valve angle (perhaps by a visual inspection) to what the sensor is telling the ecm. My guess, something wrong w/the electrical connection between the sensor & the ECM. If any ground wires have been disturbed between the engine/cylinder head and the chassis, consider that a prime suspect.
