Remove the fuel gauge sensor from the fuel tank.
Fuel level sensor resistance
Check that the resistance value between the fuel level sensor terminal and the ground terminal matches the nominal value when the sensor float is at point F (highest) and at point E (lowest).
Nominal value 2 WD:
- Point F: 3±0.6 Ohm.
- Point E: 110±2.5 ohms.
Nominal value 4 WD:
- Point F: 1.5±0.5 Ohm.
- Point E: 55±1.5 ohms.
Make sure that the resistance value changes smoothly as you slowly move the float between point F (highest) and point E (lowest).
Checking the float stroke of the fuel level sensor
Move the float and measure the height A at point F (highest) and B at point E (lowest) when the float arm touches the limiter.
Nominal value
Thermistor
Connect the fuel level sensor (thermistor) to the battery via a test lamp (12 V - 3.4 W). Immerse the sensor in water.
The condition is good if the lamp goes out when the thermistor is immersed in water and lights up when it is removed from the water.
Attention! After completing this check, dry the sensor and install it in the fuel tank.
Checking the engine coolant temperature sensor
Drain the coolant.
Remove the coolant temperature sensor.
Immerse the sensor in water at 70°C and measure the resistance.
Nominal value: 104±13.5 Ohm.
After checking, apply the specified sealant around the threads of the coolant temperature sensor.
Name of sealant: ЗМ Adhesive Nut Locking No.4171 or equivalent.
Add coolant.
