2025 Lincoln Aviator Check Engine Light Codes

The check engine light on a 2025 Lincoln Aviator can represent many issues from minor to severe. Common stored codes include P0420 (catalyst system efficiency), P0300 series (multiple misfires), P0171/P0174 (fuel trim lean conditions), and sensor-related codes for oxygen or mass airflow sensors. Ignoring these codes can escalate costs: a loose gas cap is simple and inexpensive to fix, but an unchecked lean condition can lead to turbocharger damage or burned pistons, costing thousands. Left unresolved, catalytic converter problems (P0420) often require catalytic replacement — a higher-cost repair — and can trigger failed emissions tests, preventing registration renewal. At Herb Chambers Lincoln of Westborough we use OEM diagnostic procedures to map codes to root causes quickly, so you avoid unnecessary parts replacement and repeated labor charges. Our certified Lincoln technicians explain cost-effective repair paths, including short-term fixes and recommended long-term solutions, and we clearly outline warranty coverage so you understand potential savings. We also promote relevant service specials and offer service financing to make repairs manageable. Trusting your Aviator to our factory-trained team protects performance, maintains towing capability, and preserves resale value while keeping your overall ownership costs lower than if issues are deferred or misdiagnosed.
