Attention! When removing and installing the sensor, do not touch its connector (plastic part) with the tool.
Fig. 7.12. Location of the coolant temperature sensor: A – SOHC engine; B – DOHC engine
1. Remove the coolant temperature sensor (Fig. 7.12).
2. Place the sensitive element of the sensor in hot water and measure the resistance.
Nominal resistance value:
- at a temperature of 20°C – 2.1–2.7 kOhm;
- at a temperature of 80°C – 0.26–0.36 kOhm.
3. If the resistance value differs significantly from the nominal value, replace the sensor.
4. Apply 3M NUT Locking Part #4171 or equivalent to the sensor threads.
5. Reinstall the coolant temperature sensor and tighten it to 30 Nm.
6. Connect the connector to the sensor.
