ENGINECOOLANTTEMPERATURESENSOR CHECK
1.Removetheenginecoolanttemperaturesensor.
2.Measuretheresistancebetweentheterminalsofthe
connectors while immersing the sensor part of the engine
coolanttemperaturesensorinthehotwater.
Standardvalue:
2.1-2.7kΩ(at20_C)
0.26-0.36kΩ(at80_C)
3.Iftheresistanceisnotwithintherangeofthestandard
value,replacetheenginecoolanttemperaturesensor.
