What does it mean when the engine warning light in my 2019 Holden Trax stays on?

Basically, the light is telling you that there’s something wrong with the car’s driveline and that you need to have it checked out before the problem does any permanent damage. This can be taken care of at a workshop that has the correct scanning tools.

Possible causes are numerous, but can include a dud sensor, a bad earth, wiring problems, damaged exhaust or any one of about a thousand engine or transmission glitches. Don’t bother trying to guess the reason, have the car electronically scanned and home in on the actual problem that way.
