(NAPS) — Although the check engine light may look scary lit up on the dashboard, you don’t need to panic. A glowing check engine light doesn’t mean you have to immediately pull the car to the side of the road; it does mean you should get the car checked out as soon as possible.
“Motorists should not get spooked when the check engine light comes on,” says Rich White, executive director, Car Care Council, the source for the “Be Car Care Aware” campaign promoting regular vehicle care, maintenance and repair. “When illuminated, the check engine light usually means that a vehicle system, such as the ignition, fuel injection or emission control, is not operating properly.”
Some common malfunctions that can cause the light to illuminate include a faulty oxygen sensor, mass air flow sensor, or spark plugs and wires. If the light flashes, the condition is more critical and must be checked immediately to prevent severe damage, which may include catalytic converter problems.
“Even if the vehicle appears to be running normally, ignoring the warning light could result in more costly repairs,” adds White. “At the very least, the light could be alerting you to an engine problem that is negatively impacting fuel economy and costing you money.”
Service and Solutions
When scheduling service, make sure the repair shop that examines your vehicle has professional technicians who are trained and certified in OBDII diagnosis and repair. The technician will connect your vehicle’s computer system to a diagnostic scan tool, which will provide trouble codes indicating why the check engine light was activated. While the diagnostic tool is connected, the technician can analyze data streams such as the idle speed, throttle response, engine temperature, fuel system pressure, manifold vacuum, exhaust emission levels and many other key indicators. Once the problem is identified and the repair is made, the car’s computer is reset.
