Steady light — check the basics, then get it scanned
A steady check engine light with normal driving isn't an emergency. A loose gas cap is a classic, cheap cause; otherwise get the code read soon.
⚠️ Safety first
A steady light can still be a real fault. If the temperature or oil light also comes on, treat that as urgent and stop driving.
- 1Pull over safely and check the gas cap — tighten it until it clicks, a loose cap is a common trigger.
- 2The light may take a day or two of driving to clear after you tighten the cap.
- 3Watch for any change: rough running, power loss or the light starting to flash.
- 4Get the code scanned soon (many parts stores do it free) or booked into a shop.
- 5If it starts flashing or the car runs badly, stop and request a tow.
Flashing light — stop driving and get a tow

⚠️ Safety first

- 1Ease off the throttle and get off the road as soon as it's safe.
- 2Turn the engine off once you're stopped in a safe spot.
- 3Do not keep driving to 'get it home' — misfires damage the catalytic converter quickly.
