2021 Lincoln Nautilus Check Engine Light Codes

The 2021 Lincoln Nautilus commonly logs codes related to oxygen sensors, catalytic efficiency, EVAP leaks, and ignition misfires—each carries specific risks and costs when left unaddressed. For example, a failing oxygen sensor can lower fuel economy and, if unchecked, damage the catalytic converter; repair costs escalate from a moderate sensor replacement to many hundreds for exhaust system repairs. An EVAP leak left unattended increases emissions and can cause failed inspections, while ignition misfires can harm cylinder components and the catalytic system. At Herb Chambers Lincoln of Westborough we diagnose codes using OEM scanners and present clear options: a diagnostic with an accurate estimate, OEM parts replacement, and a timeline. Addressing issues early saves on fuel and prevents cascading failures, delivering immediate savings and improved resale value. Our certified technicians are trained on Lincoln systems and software, ensuring repairs follow factory procedures. Review our service specials and schedule service to protect your Nautilus today.
