JOHN DEERE強鹿冷卻水溫度燃油溫度傳感器的作用及結構特點約翰迪爾設備故障現象檢測方法

Remove and Install Coolant Temperature Sensor
NOTE: Your engine may be equipped with either one or two coolant temperature sensor(s) (A).
The ECU monitors coolant temperature for engine protection purposes and starting. Using the coolant temperature signal, the ECU will derate engine power as coolant temperature becomes excessive. The ECU will also adjust fuel delivery during start-up during low coolant temperature conditions.
ECT Sensor
1. Disconnect coolant temperature sensor wiring A—Coolant Temperature Sensor
connector and remove sensor from thermostat housing B—Thermostat Housing
(B).
2. Coat sensor O-ring with JDT405 High Temperature Grease and install sensor in thermostat housing. Tighten to specifications.
Specification
Coolant Temperature Sensor—
Torque ............................................................................  10 N•m (7.5 lb-ft)
3. Install sensor wiring connector.

Remove and Install Fuel Temperature Sensor (Dual Rail System)
The ECU monitors fuel temperature to determine fuel density and adjust delivery as necessary.
1. Disconnect fuel temperature sensor wiring connector and remove sensor from fuel manifold (A).
NOTE: Plug bore with clean cap plug after removal of sensor.
2. Coat sensor O-ring with JDT405 High Temperature Grease and install sensor in fuel manifold. Tighten to specifications.
Specification
Fuel Temperature Sensor-to-Fuel Manifold (Dual Rail Fuel
System)—Torque............................................................  10 N•m (7.5 lb-ft)
3.  Install sensor wiring connector.

Remove and Install Fuel Temperature Sensor (Single Rail System)
The ECU monitors fuel temperature to determine fuel density and adjust delivery as necessary.
1. Disconnect fuel temperature sensor wiring connector and remove sensor from fuel filter housing.
NOTE: Plug bore with clean cap plug after removal of sensor.
2. Coat sensor O-ring with JDT405 High Temperature Fuel Temperature Sensor
Grease and install sensor in fuel filter housing. Tighten to specifications.
Specification
Fuel Temperature Sensor-to-Fuel Filter Housing (Single Rail Fuel
System)—Torque.............................................................  14 N•m (10 lb-ft)
3. Install sensor wiring connector.
