4-4-52 Liquid Pipe Temperature sensor error (Open/Short)
1. Cause of problem
Did the connector for the Liquid Pipe
Temperature sensor break away
from the PCB?
Did the resistance
value significantly stray from the following
temperature table?
Separate the connector of the Liquid Pipe Temperature
sensor from the PCB and measure the resistance value
between the 2 terminals.
Restart operation after replace the PCB
Restart operation after connecting
the connector to PCB
Replace this part as it is the defective of
the Liquid Pipe Temperature sensor itself.
