The check engine light on a Land Rover signals a problem within the vehicle’s engine or emissions system. Common causes include a loose gas cap, faulty oxygen sensor, or ignition issues. While some triggers are minor, others may lead to serious engine damage. Prompt diagnostics by a professional are essential to identify the issue and prevent further complications.

1. WHAT DOES THE
CHECK ENGINE LIGHT
MEAN ON A LAND
ROVER?

2. The check engine light (CEL) on your Land Rover is
more than just an alert. It's a signal from your
vehicle’s onboard diagnostics system indicating
something isn't working as it should. While it doesn’t
always point to a serious failure, ignoring it can lead to
expensive consequences.

3. Common Causes of a
Check Engine Light

4. Loose or Damaged Gas Cap

5. A simple issue like a
loose or cracked gas cap
can disrupt fuel pressure
and trigger the CEL.

6. Faulty Oxygen or Mass
Airflow Sensor

7. These components
regulate air-fuel mixture;
failure can reduce
performance and increase
emissions.

8. Engine and Emissions
System Concerns

9. Malfunctioning Catalytic
Converter

10. A damaged converter
impacts engine efficiency
and emissions, often
resulting in a flashing CEL.

11. Ignition System Failures

12. Worn spark plugs or faulty
ignition coils can cause
misfires, poor fuel
economy, and rough idling.

13. What You Should Do

14. Don’t ignore it—schedule
a diagnostic scan
immediately to pinpoint
the cause.

15. A flashing light often
signals a more urgent issue
that could cause further
damage if the vehicle is
driven.

16. Conclusion

17. A check engine light on
your Land Rover may seem
minor but often indicates
underlying issues that
need expert attention.

18. Timely diagnosis ensures
continued performance,
safety, and long-term
reliability.
