To resolve a heat-sensitive Renault DF357 fault code without replacing functioning components unnecessarily, follow this structured diagnostic approach:
Ensure the wiring harnesses leading to the transmission are secure and free of corrosion. renault df357 hot
Use a heat gun or a hair dryer to gently warm the sensor body while watching the multimeter. If the resistance fluctuates wildly, spikes to infinity, or drops to zero as the temperature rises, the internal electronics are failing under heat stress, and the sensor must be replaced.
