Check Engine Light Flashing

The flashing check engine light on a 2016 Lincoln MKX is an urgent indicator that the engine is misfiring or that a condition exists which could cause severe catalytic converter damage. A flashing light typically means the engine is running poorly right now — reduced power, rough running, or excessive emissions — and immediate attention is recommended. At Herb Chambers Lincoln of Westborough our technicians perform a prioritized diagnostic to identify ignition faults, fuel delivery problems, or sensor failures. Because our service center stocks OEM parts and follows Lincoln factory procedures, repairs are precise and reduce the likelihood of repeat visits. We also explain the immediate cost and the long-term savings of timely repair: preventing a failed catalytic converter or further engine damage avoids repair bills that can far exceed the initial fix. Take advantage of our current service specials and ask about service financing to address issues now and protect your investment in a way that fits your budget.

2016 Lincoln MKX Check Engine Light Codes
