What Happens in Engine Fail Safe Mode:
* Reduced Engine Power: The most noticeable effect is a significant drop in engine power. This is to prevent further damage to the engine and ensure safe driving.
* Limiting RPM: Your Navigator's RPMs (Revolutions Per Minute) will be restricted, preventing the engine from exceeding a certain limit.
* Warning Lights: The check engine light will illuminate on the dashboard, and possibly other warning lights as well, indicating a potential issue.
* Potential Drivability Issues: You may experience rough idle, hesitation during acceleration, or even difficulty starting the vehicle.
Why Engine Fail Safe Mode Activates:
The computer activates Fail Safe Mode for a variety of reasons, including:
* Sensor Malfunctions: Faulty sensors, like the oxygen sensor, mass airflow sensor, or throttle position sensor, can send incorrect information to the computer, leading to it limiting engine operation.
* Electrical Issues: Loose connections, wiring problems, or even a failing battery can trigger the Fail Safe Mode.
* Engine Components Failing: Issues with fuel injectors, ignition coils, or other vital engine parts can cause the computer to activate Fail Safe Mode.
* Engine Oil Pressure Problems: Low oil pressure can be a serious issue, and Fail Safe Mode will activate to prevent further damage.
What You Should Do:
1. Pull Over Safely: As soon as possible, safely pull over to the side of the road. Avoid continuing to drive with the engine in Fail Safe Mode.
2. Check the Dashboard: Observe the warning lights and any accompanying messages on your dashboard.
3. Consult Your Owner's Manual: Your owner's manual might provide more specific instructions for your vehicle's Fail Safe Mode.
4. Call a Mechanic: Contact a trusted mechanic or a qualified technician as soon as possible. They will need to diagnose the issue and make any necessary repairs.
Important Note:
* Do not try to fix the issue yourself unless you are a trained mechanic. Attempting repairs without the necessary knowledge and tools can further damage your vehicle.
* Driving with the engine in Fail Safe Mode for extended periods is not recommended. It can cause further damage and lead to more expensive repairs.
By understanding what Engine Fail Safe Mode means, you can be prepared to react appropriately and ensure the safety of yourself and others while getting your Lincoln Navigator back on the road.
