Removal of water temperature sensor unit
1. Remove the negative cable of battery;
2. Disconnect the connection of connector;
3. Remove the water temperature sensor.
Installation of water temperature sensor
1. Apply sealant onto surface between the 3
rd
screw thread and the top.
2. Install the water temperature sensor;
Tightening torque:
11.8-17.6N.m{120-180kgf.cm, 105-156in.lbf}
3. Connect the connector of water temperature
sensor;
4. Connect the negative cable of battery.
Check of water temperature sensor
1. Remove water temperature sensor;
2. Place the sensor into a water receptacle;
3. Gradually heat water in the receptacle.
4. Measure with an ohmmeter and identify the
resistance value between the sensor terminal
and sensor housing as shown in the following
Table. If it fails to meet the technique
requirements, replace the water temperature
sensor.
Water temperature Resistance
49.8-50.2{121.7- 122.3} 189.4-259.6
In terms of engine TRITEC, except the water
temperature sensor, it is also necessary to check the
water temperature signal from the ECU, by
methods shown specifically as below:
1. Connect by use of an oscillograph, with the end
of signal acquisition connected to PIN 3E, the
other end to body ground;
2. Start up the engine and observe the duty cycle
(active low) of oscillograph frequency. It runs
properly if the following requirements are met:

If the relativity between the duty cycle and water
temperature is correct, but the indication is wrong,
please verify firstly whether the pointer indicates the
zero (the method is same as the inspection method
of tachometer). If the zero indication is correct, it
means that the combination instrument is damaged.
Replace the combination instrument. If the correct
indication of null cannot be assured, please align
first the pointer and recheck. If the problem persists,
it indicates that the combination instrument is
damaged. Replace the combination instrument.
If the relativity between the duty cycle and water
temperature is incorrect, please check for proper
connection of harness. If the connection of harness
is correct, it means that there are problems in ECU,
please maintain or replace ECU by referring to the
part ECU- Power System Maintenance
