On-Board Engine Diagnostics and Performance
All vehicles manufactured after 1996 have what is known as an on-board diagnostics system. While this might be news to you, the ‘check engine’ light or the ‘service engine soon’ light probably isn’t.
Engine Diagnostics
The on-board diagnostics system is a computer system which monitors and records engine performance. Any discrepancy is recorded. Those engines with no routine maintenance are more likely to trigger the ‘check engine’ light because of sub-par engine performance. By having engine diagnostics run by qualified staff, repairs and maintenance can be performed to keep the engine running optimally. The engine diagnostics provide trouble codes which describe the malfunctioning component. Tune-ups are the best way to ensure the engine operates efficiency and to avoid the ‘check engine’ light. A tune-up typically includes spark plug replacement, fuel filter replacement, air filter replacement, spark plug wires replacement, as well as, belts and hose replacement. Simply by performing regular maintenance can greatly extend the lifespan of your vehicle’s engine.
Some common problems which can cause the trouble codes to be registered in the computer system are slow engine cranking, stalling, knocking, rough idle, or engine pinging during acceleration. These can all be indicative of an engine in need of servicing. When drivers recognize they are getting lower gas mileage can also be an indicator that something is wrong with the engine just as recognizing the loss of power during acceleration can be. Warning lights are the obvious indicators that the engine is not operating at an optimal level but paying attention to the other indicators can be just as important.
