6-1) If the measured value is not normal,
Replace the ETS with the new one, recheck.
If the measured value is normal,
Check the G/L electric wire, W/R electric wire to see if they have been broken or have short-circuited or if
the ECU coupler is a bad contact ( No.4, No. 20.)
If the electric wire is no problem, ECU is broken.
Replace ECU with the new one, recheck.
6-2) After fault repaired, To erase the memorized fault code in the ECU is refer to how to remove the fault code(5-10).

Disassemble the ETS(Engine Temperature Sensor) : (Refer to 4-20)
2) Check the ETS(Engine Temperature Sensor)
Connect two terminals of ETS to the probe of the tester and insert even its screw point of ETS into oil.
Read the temperature of thermometer depending upon oil temperature’s change and tester’s value.
Characters of ETS
Measuring unit of resistance : Resistance ‘ R ‘[k ]
If the value of resistance is high or out of the standard value, replace the ETS with the new one.
1)Be careful do not fell down the ETS, because its weakness.
2)Be careful the ETS and the Thermometer do not to touched to oil bowl.
3)Be careful oil temperature will not raised more than measurement temperature.
3) Install
Install in the reverse order of removal with standard torqve.
