The first thing to do when you see the “check engine” light come on is to stay calm. This sensor is part of your car’s on-board diagnostic system, constantly monitoring engine performance, air to fuel ratio, and ignition timing. This little light is there to alert you that a “fault” has been noticed within the system.
Can you continue to drive when you see the “check engine” light come on? Unless the engine is overheating, go ahead and continue to your destination. But be sure to make an appointment for an engine diagnostic test to pinpoint a potential issue. It’s safe to say that the majority of times the “check engine” light comes on is a relatively simple and inexpensive fix.
Here are some tips on what to do when your “check engine” light comes on:
- Try tightening your gas cap. A loose gas cap can trigger a sensor causing the “check engine” light to illuminate. If the gas cap is broken, it should be replaced.
- Inspect the gauges. If one of the gauges on your instrument panel shows an abnormal reading, pull over instantly, and turn off the motor.
- Reduced engine performance. If your vehicle is loosing power, slow down, and avoid towing or carrying heavy cargo.
- Postpone emissions test. Your vehicle will possibly fail the emissions test so delay to schedule the test until your car is checked and repaired and the light goes off.
- Schedule diagnostic tests. Is the “check engine” light on all the time, or does it flash intermittently? If the light is flashing, your car wants instant attention. If the light is solid, you can keep driving for a little while, but schedule an inspection as soon as possible.
