Radiator Coolant Temperature Sensor Circuit

Descripción

This code indicates an issue with the electrical circuit for the radiator coolant temperature sensor. This sensor tells the car's computer how hot the coolant is, which is important for engine performance and cooling system operation.

Pasos de reparación

1. 1 Inspect the radiator coolant temperature sensor connector for corrosion, looseness, or damage and clean or reseat it as needed.
2. 2 Check the wiring harness running to the radiator coolant temperature sensor for frayed, broken, or shorted wires and repair as needed.
3. 3 Test the radiator coolant temperature sensor with a multimeter to verify it is reading within the correct resistance range for the current coolant temperature.
4. 4 Replace the radiator coolant temperature sensor if it is reading out of specification.
5. 5 Check for related trouble codes and inspect the ECM grounds and power supply for issues.
6. 6 Have the engine control module (ECM) professionally tested and reprogrammed or replaced if all other components test normal.
