ECT Sensor Removal and Installation
B947H11306011
Removal
1) Remove the left side cowling. Refer to “Exterior
Parts Removal and Installation” in Section 9D
(Page 9D-6).
2) Drain engine coolant. Refer to “Cooling System
Inspection” in Section 0B (Page 0B-12).
3) Disconnect the coupler and remove the ECT sensor
(1).
CAUTION
!
Take special care when handling the ECT
sensor. It may cause damage if it gets an
excessive impact.
Installation
Install the ECT sensor in the reverse order of removal.
Pay attention to the following points:
• Tighten the ECT sensor (1) to the specified torque.
CAUTION
!
Use new gasket washer to prevent engine
coolant leakage.
Tightening torque
ECT sensor (a): 18 N·m (1.8 kgf-m, 13.0 lbf-ft)
• Pour engine coolant. Refer to “Cooling System
Inspection” in Section 0B (Page 0B-12).
ECT Sensor Inspection
B947H11306012
Refer to “DTC “C15” (P0115-H/L): ECT Sensor Circuit
Malfunction” in Section 1A (Page 1A-50).
Inspect the ECT sensor in the following procedures:
1) Remove the ECT sensor. Refer to “ECT Sensor
Removal and Installation” (Page 1C-4).
2) Connect the ECT sensor (1) to the circuit tester and
place it in the oil (2) contained in a pan, which is
placed on a stove.
3) Heat the oil to raise its temperature slowly and read
the column thermometer (3) and ohmmeter.
If the ECT sensor ohmic value does not change in
the proportion indicated, replace it with a new one.
CAUTION
!
• Take special care when handling the ECT
sensor. It may cause damage if it gets an
excessive sharp impact.
• Do not contact the ECT sensor and column
thermometer with a pan.
