3. Step-by-Step DIY Repair Guide for RAM 1500 TRX
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 RAM 1500 TRX equipped with 6.2L Supercharged HEMI V8 (702HP / 650 lb-ft / Bilstein Black Hawk e2).
Unplug sensor connector while watching live data. If temperature drops to -40°F (-40°C), the sensor itself is shorted. on the RAM 1500 TRX equipped with 6.2L Supercharged HEMI V8 (702HP / 650 lb-ft / Bilstein Black Hawk e2).
If reading stays pegged at max with sensor unplugged, inspect harness for pinch points grounding against engine block. on the RAM 1500 TRX equipped with 6.2L Supercharged HEMI V8 (702HP / 650 lb-ft / Bilstein Black Hawk e2).
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 RAM 1500 TRX equipped with 6.2L Supercharged HEMI V8 (702HP / 650 lb-ft / Bilstein Black Hawk e2).
Bleed air from cooling system, clear DTCs, and verify normal temperature rise on live data. on the RAM 1500 TRX equipped with 6.2L Supercharged HEMI V8 (702HP / 650 lb-ft / Bilstein Black Hawk e2).

4. RAM 1500 TRX P0117 FAQs
What causes code P0117 to trigger on a RAM 1500 TRX?
On the RAM 1500 TRX (6.2L Supercharged HEMI V8 (702HP / 650 lb-ft / Bilstein Black Hawk e2)), 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 RAM 1500 TRX?
On the RAM 1500 TRX, the 16-pin DLC diagnostic connector is located Driver lower dash assembly next to hood release lever. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my RAM 1500 TRX 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.
