Diagnostic tests are essential to maintaining your vehicle's health and preventing costly repairs down the road. These tests can reveal problems within your car's engine, transmission, exhaust system, brakes, and other significant components, as well as performance issues with the fuel injector, air flow and coolant, ignition coils, and throttle.

Our experienced auto mechanic technicians will perform a thorough inspection of your vehicle to identify any issues that may be affecting its performance. At John's Automotive Care, we understand the importance of regular diagnostic tests to keep your vehicle running smoothly. That's why we recommend bringing your car in for a diagnostic check at least once a year, even if there are no warning lights on your dashboard. This allows us to identify any minor issues that may not trigger the check engine light and address them before they become major problems. Our advanced diagnostic tools also enable us to check your car's computer system for manufacturer notifications or stored information about the car's history, providing a complete picture for the best possible auto repair.
