4-3-11 Emission temperature sensor error
1. Inspection items
1) Are the sensors connected properly?
2) Are the sensors located properly?
3) Do the resistance values of the sensors satisfy each temperature?
2. Inspection order
Yes
Yes
Yes
Replace temperature sensor
No
Reconnect the temperature sensor
connector
No
Power off
Reconnect the temperature sensor
connector
No
No
Yes
Are connectors
properly connected to the
relevant colors?
Are temperature sensors
connected without separation?
When measuring
the resistance of both sides with a single
temperature sensor, does it indicate 200KΩ at
room temperature of 25°C?
Yes
Replace PCB after turning off the power
No
After assembling
the temperature sensors on PCB check
the voltage of both sides. Do they indicate
DC1V~DC4V?
Is there a
short circuit or defective contact in
the sensor wires?
Replace temperature sensor after turning
off the power
Yes
Power on
Replace PCB after turning off the power
ex) Room temperature
23°C ~ resistance 205.4kΩ
