3. Step-by-Step DIY Repair Guide for Lincoln Aviator
Read ECT live PID on scanner. If it reads 284°F (140°C) or higher with engine cold, a short to ground exists. on the Lincoln Aviator equipped with 3.0L Twin-Turbo EcoBoost V6 (400HP) / Grand Touring PHEV (494HP).
Unplug sensor connector while watching live data. If temperature drops to -40°F (-40°C), the sensor itself is shorted. on the Lincoln Aviator equipped with 3.0L Twin-Turbo EcoBoost V6 (400HP) / Grand Touring PHEV (494HP).
If reading stays pegged at max with sensor unplugged, inspect harness for pinch points grounding against engine block. on the Lincoln Aviator equipped with 3.0L Twin-Turbo EcoBoost V6 (400HP) / Grand Touring PHEV (494HP).
Allow engine to cool, unscrew old ECT sensor from coolant crossover pipe or thermostat housing, install new OEM sensor with fresh thread sealant. on the Lincoln Aviator equipped with 3.0L Twin-Turbo EcoBoost V6 (400HP) / Grand Touring PHEV (494HP).
Bleed air from cooling system, clear DTCs, and verify normal temperature rise on live data. on the Lincoln Aviator equipped with 3.0L Twin-Turbo EcoBoost V6 (400HP) / Grand Touring PHEV (494HP).

4. Lincoln Aviator P0117 FAQs
What causes code P0117 to trigger on a Lincoln Aviator?
On the Lincoln Aviator (3.0L Twin-Turbo EcoBoost V6 (400HP) / Grand Touring PHEV (494HP)), P0117 is most frequently caused by ECT sensor internal short to ground or Short circuit to ground in ECT signal wiring harness.
Where is the OBD-II port located on my Lincoln Aviator?
On the Lincoln Aviator, the 16-pin DLC diagnostic connector is located Driver lower kick panel near door release assembly. 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 Aviator with code P0117?
No. The ECU thinks the engine is at 280°F+ (overheating) and runs rich or disables cooling fan logic. Given that P0117 carries a High severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
