When your check engine light comes on, your vehicle’s computer has detected a problem within the engine, fuel system, emissions system, or electronic network. Even if your vehicle continues to run normally, the system is recording fault data that needs attention.
At Restivo’s Wrenches LLC, we provide advanced diagnostic testing for vehicles throughout Prescott and surrounding Northern Arizona communities. Our focus is identifying the real cause of the warning light so repairs are accurate and not based on guesswork.
