Engine Electrical Devices: 1C-6
Installation
Install the ECT sensor in the reverse order of removal.
Pay attention to the following points:
• Tighten the ECT sensor to the specified torque.
CAUTION
!
Use new O-ring (1) to prevent engine coolant
leakage.
Tightening torque
ECT sensor (a): 12 N·m (1.2 kgf-m, 8.5 lbf-ft)
• Install the exhaust pipe. Refer to “Muffler / Exhaust
Pipe Removal and Installation” in Section 1K
(Page 1K-2).
• Pour engine coolant. Refer to “Cooling System
Inspection” in Section 0B (Page 0B-9).
ECT Sensor Inspection
BA02J21306013
Refer to “DTC “15” (P0115-H/L): ECT Sensor Circuit
Malfunction” in Section 1A (Page 1A-34).
Inspect the ECT sensor in the following procedures:
1) Remove the ECT sensor. Refer to “ECT Sensor
Removal and Installation” (Page 1C-5).
2) Connect the ECT sensor (1) to the multi 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.
