Mitsubishi Lancer persistent check oil warning despite full oil levels and running on 2 cylinders on Mitsubishi Lancer

Some Mitsubishi Lancer owners report experiencing a persistent check oil warning even when oil levels are full and the engine is running on 2 cylinders. This warning may indicate underlying problems, such as issues with the engine's performance due to operating on only 2 cylinders, which can lead to further engine damage if not addressed. Additionally, a faulty oil pressure sensor may trigger false warnings, prompting the need for inspection and potential replacement. Some owners also find that problems with the engine control unit can cause erroneous warnings, necessitating a diagnostic check of the ECU. If these issues persist, it is advisable for owners to consult a qualified mechanic or dealership for a thorough inspection to identify and resolve the underlying cause of the warning light.
