4. Lincoln Navigator P0201 FAQs

What causes code P0201 to trigger on a Lincoln Navigator?

On the Lincoln Navigator (3.5L Twin-Turbo EcoBoost V6 (440HP / 510 lb-ft torque)), P0201 is most frequently caused by Failed, open, or shorted fuel injector solenoid on Cylinder 1 or Damaged or chewed wiring harness to Cylinder 1 injector.

Where is the OBD-II port located on my Lincoln Navigator?

On the Lincoln Navigator, the 16-pin DLC diagnostic connector is located Under driver side dashboard kick panel. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.

Can I safely drive my Lincoln Navigator with code P0201?

No. Dead injector on Cylinder 1 causes immediate dead misfire, severe shaking, and unburned air/fuel delivery imbalance. Given that P0201 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
