The Thermo King alarm 06 describes the following behavior:
| Código de Alarma 06 | |
|---|---|
| Verde=OK | Check the engine coolant temperature sensor. |
| Report the alarm at the end of the day. |
Cause of Fault Code 6 Thermoking:
- Open circuit.
- Short circuit.
When the Thermoking system uses a PT1000-type sensor, the system module detects an open circuit problem when the resistance measurement of the sensor circuit is above 1300 Ω. The short circuit of the sensor is detected when the sensor circuit resistance is below 602 Ω.
- The sensor cannot be examined without disconnecting it.
- The sensor is a Pt1000, and it has a positive temperature coefficient, meaning that the electrical resistance of the sensor increases with temperature.
- Rubbing the tip of the sensor with your hands should increase the resistance.
- You can disconnect both sensors and check their resistance, which should give, in most cases, the same value.
- The sensor is calibrated to have a resistance of 1,000 Ω at 0 °C.
Check that the temperature sensors have voltage supply, verify the value, and compare with other nearby temperature sensors.
