Engine Coolant Temperature (Ect) Sensor Removal And Installation; Engine Coolant Temperature (Ect) Sensor Inspection - Suzuki 2006 SX4 Service Manual

3) Measure output voltage variation while accelerator
pedal is released and fully depressed as the
following graph.
If sensor voltage is out of specified value or does not
vary linearly as the following graph, replace APP
sensor assembly.

Engine Coolant Temperature (ECT) Sensor
Removal and Installation
Removal
1) Disconnect negative cable at battery.
2) Drain coolant referring to "Cooling System in Section
1F".
WARNING
!
To avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot.
Scalding fluid and steam can be blown out
under pressure if cap is taken off too soon.
3) Disconnect connector from ECT sensor (1).
4) Remove ECT sensor from water outlet cap.

Engine Electrical Devices:
Installation
Reverse removal procedure noting the following.
• Clean mating surfaces of ECT sensor and water outlet
cap.
• Check O-ring for damage and replace, if necessary.
• Tighten ECT sensor (1) to specified torque.
Tightening torque
ECT sensor (a): 12.5 N·m (1.25 kgf-m, 9.0 lb-ft)
1, (a)
• Connect connector to ECT sensor securely.
• Refill coolant referring to "Cooling System Flush and
Refill in Section 1F".
Engine Coolant Temperature (ECT) Sensor
Inspection
Immerse temperature sensing part of ECT sensor in
water (or ice) and measure resistance between sensor
terminals while heating water gradually.
If measured resistance doesn't show such characteristic
as shown, replace ECT sensor.
