Inspection
1. | Turn the ignition switch OFF.
2. | Remove the ECTS (Refer to "Removal").
3. | After immersing the thermistor of the sensor into engine coolant, measure resistance between the ECTS terminals 3 and 4.
4. | Check that the resistance is within the specification.
Specification: Refer to “Specification”
Removal
1. | Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2. | Remove the air cleaner assembly and air intake hose. (Refer to Engine Mechanical System - “Air Cleaner”)
3. | Relax the engine wiring.
(1) | Disconnect the ignition coil (A).
(2) | Disconnect the OCV (B).
(3) | Disconnect the CMPS (C).
(4) | Disconnect the FPCV (D).
(5) | Disconnect the PCSV (E).
(6) | Remove the engine wiring installation bolts (F) and then remove the engine wiring harness (G).
4. | Remove the vacuum pipe installation bolts (A) and relax the bracket.
5. | Disconnect the engine coolant temperature sensor connect (B).
6. | Remove the engine coolant temperature sensor (C).
• | Note that engine coolant may be flowed out from the water temperature control assembly when removing the sensor.
7. | Fill with engine coolant. (Refer to Engine Mechanical System - "Coolant")
Installation
• | Install the component with the specified torques.
• | Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
• | Apply the engine coolant to the O-ring.
• | Insert the sensor in the installation hole and be careful not to damage.
1. | Installation is reverse of removal.
Engine Coolant Temperature Sensor installation : 29.4 ~ 39.2 N.m (3.0 ~ 4.0 kgf.m, 21.7 ~ 28.9 lb-ft)
