Mitsubishi Galant Fortis Check Engine Light Malaysia

A check engine light on the Galant Fortis can indicate a wide range of issues — from a loose fuel cap to a faulty oxygen sensor, MIVEC solenoid issue, or catalytic converter efficiency fault on high-mileage units. An OBD-II scan will retrieve the specific fault code. Do not ignore a solid check engine light, and never drive with a flashing check engine light (which indicates an active misfire that can damage the catalytic converter). On a high-mileage unit, O2 sensor faults are among the most common causes.
