Co oznacza ten kod błędu?
The CPM reads the DC voltage coming from the heater's coolant temperature sensor. The fault is set when the signal is too high, for example when the cable is shorted to supply voltage or has a break. The heater's function is blocked.
Możliwe przyczyny
- Contact resistance and oxidation in the connections
- Break in the wiring
- Wiring shorted to supply voltage
- Damaged coolant temperature sensor
Co możesz zrobić
- 1Check the coolant level and mixture
- 2Check the wiring visually for damage and make sure the insulation is intact
- 3Use a multimeter to check that the cable to the sensor carries no voltage when the ignition is off; if it does, the cable is shorted to positive
- 4Check that the connectors at the sensor and the heater are secure and free from oxidation
- 5If the sensor is damaged or its resistance is wrong, have a workshop replace the coolant temperature sensor
