Insufficient fuel combustion may cause smoke from the parking heater. In this case, it is possible to adjust the fuel injection rate of the oil pump appropriately, or if the battery voltage or current is not sufficient to reach the temperature of the spark plug, resulting in mixed fuel and gas combustion and smoke production.
There are three reasons for the malfunction of the parking heater, namely incorrect connection of the flame sensor, short circuit or open circuit of the flame sensor wire, and damage to the flame sensor.
If the flame sensor is not connected correctly, first check if the wiring harness or plug is connected correctly and if the wires are loose.
If the lead of the flame sensor is short or open, the simplest detection method is to use a multimeter to check the lead of the flame sensor to see if it is short or open.
If there is any damage, it is recommended to replace or repair it in a timely manner. If the flame sensor is damaged, a multimeter can also be used to check if the flame sensor is damaged. Suggest timely replacement. It should be noted that if the car is idling for a long time, it is recommended not to use the air conditioning system inside the car, as this can cause certain damage to the air conditioning system.
