Checking the operation of the temperature gauge
1. Disconnect the connector from the temperature sensor.
2. Turn on the ignition. The arrow of the temperature gauge should point to the position "COOL".
3. Through a 3 W test lamp, ground the connector pin on the wire side.
4. Turn on the ignition, check that the control lamp is on and the pointer arrow moves to the mark "NOT".
5. Replace the sensor, led the work of the pointer is different from the description.
6. Then check the system again. If the pointer does not work as described, measure the pointer resistance.
Checking the resistance of the temperature gauge
Measure the resistance between the leads:
Models up to 1996
Resistance between pins:
- T—E ~214 Ohm
- T—IG ~75 Ohm
- E—IG ~139 Ohm
Models after 1996
Resistance between pins:
- A-B ~58.5 ohm
- A—C ~175 Ohm
- V—C ~102, Ohm
If the resistance is not as specified, replace the pointer.
Checking the coolant temperature sensor
Measure the resistance between the terminal and the sensor housing. Rated resistance:
- at 50°C: 160-240 Ohm
- at 120°C: 17.1-21.2 ohms
Note: resistance values are given for models from 1996.
