Other issues can trigger the check engine light on a Fiat, such as:

Poor fuel: Low-quality gasoline can trigger the CEL on Fiat vehicles
Turbo problem: Under boost pressure
Thermostat: Engine overheats or takes too long to reach operating temperature
Oxygen sensor: Increases emissions, a decrease in fuel economy.
Mass airflow sensor: Often results in multiple codes and poor throttle response

This indicator is part of the onboard diagnostics (OBD-II) system and in all cases it indicates a problem with your emissions system. Basically, it is an emissions monitoring system. A Check Engine indicator will stay solid or blink.
