ENGINE COOLANT TEMPERATURE SENSOR

REMOVAL

• Drain engine coolant. (#2-17)
• Remove the seat. (#6-4)
• Remove the fuel tank right side cover.
• Remove the IAP sensor vacuum damper.
• Disconnect the engine coolant temperature sensor lead wire
coupler.
• Place a rag under the sensor and remove the engine coolant
temperature sensor 1.

INSPECTION

• Check the engine coolant temperature by testing it at the
bench as shown in the figure. Connect the temperature sen-
sor 1 to a circuit tester and place it in the water contained in a
pan, which is placed on a stove.
• Heat the water to raise its temperature slowly and read the
column thermometer 2 and the ohmmeter.
• If the temperature sensor ohmic valve does not change in the
proportion indicated, replace it with a new one.

* Take special care when handling the temperature
sensor. It may cause damage if it gets a sharp
impact.
* Do not contact the engine coolant temperature sen-
sor 1 and the column thermometer 2 with a pan.

INSTALATION

• Install a new sealing washer 1.
• Tighten the engine coolant temperature sensor to the speci-
fied torque.
