Check Engine Light Flashing

The check engine light flashing on a 2016 Lincoln Navigator signals an active misfire or a condition that can cause immediate engine damage or excessive emissions. When the lamp flashes, unburned fuel is entering the exhaust system which can overheat and damage the catalytic converter; ignoring a flashing light can escalate repair costs and risk leaving you stranded. At Herb Chambers Lincoln of Westborough our priority is rapid, accurate diagnosis to limit secondary damage. Using OEM-grade scan tools and factory repair procedures, our certified technicians can determine whether the issue is a misfiring ignition coil, failing spark plug, fuel delivery problem, or sensor fault. We communicate clear, itemized estimates and discuss immediate versus scheduled repairs so you understand immediate and long-term savings. For customers concerned about cost, we offer service financing to spread payments and available service specials that reduce out-of-pocket expense. Because flashing conditions can indicate urgent risk, we recommend you schedule appointment as soon as possible so our team can protect your vehicles engine and get you safely back on the road.

2016 Lincoln Navigator Check Engine Light Codes

Common check engine light codes for a 2016 Lincoln Navigator include P0300 (random/multiple cylinder misfire), P0171/P0174 (fuel trim/system lean), P0420 (catalyst efficiency below threshold), and P0421 or sensor-related codes tied to oxygen sensors or EVAP system faults. Each code represents distinct risks: misfires (P0300) can damage pistons and catalytic converters if left unchecked; lean conditions (P0171/P0174) reduce performance and fuel economy and can indicate vacuum leaks or fuel delivery problems; a P0420 left unresolved can lead to failed emissions tests and more expensive exhaust repairs over time.

We provide line-item estimates that highlight immediate repairs and the long-term savings of using OEM parts and certified labor.
