The EVAP/EGR/CAT/O2 fail inspection, the fuses are and there is no check engine

Question

The EVAP/EGR/CAT/O2 fails inspection, the fuses are and there is no check engine. Do I need an engine calibration?

Answer 1

Why did the inspection component fail? Sometimes the problem is that the vehicle has not been driven enough to complete the test, if that is the case then you need to drive your vehicle more without clearing the codes or disconnecting the car battery prior to having the test done. If the inspection fails, then you need to replace the failed component.
