4) Remove the ECT sensor (2).
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 the new gasket washer (2) to prevent
engine coolant leakage.

ECT sensor (a): 18 N·m (1.8 kgf-m, 13.0 lbf-ft)
ECT Sensor Inspection
B944H11306009
Refer to “DTC “C15” (P0115-H/L): ECT Sensor Circuit
Malfunction in Section 1A (Page 1A-47)”.
Inspect the ECT sensor in the following procedures:
1) Remove the ECT sensor. Refer to “ECT Sensor
Removal and Installation (Page 1C-3)”.
2) Connect the ECT sensor (1) to a 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 the ohmmeter.
If the ECT sensor ohmic valve 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 the
column thermometer with a pan.
