Radiator Coolant Temperature Sensor Circuit Low

Descripción

This code indicates that the radiator coolant temperature sensor is reporting a temperature that is too low. The car's computer is receiving a signal that suggests the engine is colder than it actually is, which can affect fuel mixture and engine operation.

Pasos de reparación

1. 1 Check coolant level and top off if low, as insufficient coolant can cause inaccurate temperature readings.
2. 2 Inspect the wiring harness and electrical connector at the radiator coolant temperature sensor for corrosion, damage, or loose connections.
3. 3 Test the radiator coolant temperature sensor circuit with a multimeter to verify proper voltage and resistance readings match manufacturer specifications.
4. 4 Replace the radiator coolant temperature sensor if it is reading out of range or has failed.
5. 5 Inspect and test the thermostat for proper operation; replace if stuck open, as this can cause consistently low temperature readings.
6. 6 Repair or replace any damaged wiring in the coolant temperature sensor circuit if open or short circuits are found.
