3. Step-by-Step DIY Repair Guide for Hyundai Palisade
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 Hyundai Palisade equipped with 3.8L V6 GDI (Lambda II 291HP / 262 lb-ft torque).
Unplug sensor connector while watching live data. If temperature drops to -40°F (-40°C), the sensor itself is shorted. on the Hyundai Palisade equipped with 3.8L V6 GDI (Lambda II 291HP / 262 lb-ft torque).
If reading stays pegged at max with sensor unplugged, inspect harness for pinch points grounding against engine block. on the Hyundai Palisade equipped with 3.8L V6 GDI (Lambda II 291HP / 262 lb-ft torque).
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 Hyundai Palisade equipped with 3.8L V6 GDI (Lambda II 291HP / 262 lb-ft torque).
Bleed air from cooling system, clear DTCs, and verify normal temperature rise on live data. on the Hyundai Palisade equipped with 3.8L V6 GDI (Lambda II 291HP / 262 lb-ft torque).

Where is the OBD-II port located on my Hyundai Palisade?
On the Hyundai Palisade, 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 Hyundai Palisade 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.
