For the past week or so, I noticed that my car engine check light stays on for longer than usual. Should I be worried?

The engine check light comes on whenever the engine control unit detects a fault or error.

It could be something as simple as a leak in the intake air hose or something a little more complex, such as an issue with the throttle position sensor.

If the light comes on intermittently or stays momentarily, it is likely a problem that is not serious. However, it means a fault does exist.

It is always advisable to determine the exact cause of the warning and rectify the problem as the faulty component could affect engine performance, emissions and fuel economy over time.

Take the car to a workshop that has the facility to conduct an electronic on-board diagnosis.
