A) Disconnect the fuel level sensor connector. Connect «+» voltmeter to terminal 2 of the connector, «-» voltmeter to ground.
b) turn on the ignition: the voltmeter needle should fluctuate around the 4.5 V mark. If not, remove and check the pointer.
2. Checking the resistance of the pointer. Measure the resistance between terminals FU and IG.
- Resistance: about 55 ohm
If the resistance is not as specified, replace the pointer.
3. Checking the resistance of the sensor.
A) Check the change in sensor resistance when moving its float.
b) Measure the resistance between terminals 1 and 2 of the sensor.
