Fuel level sensor resistance
Check the correspondence of the resistance value between the output of the fuel level sensor and the output «masses» nominal value when the float of the sensor is at point F (highest) and at point E (inferior).
Rated value 2WD:
- F point: 3±0.6 ohm.
- Point E: 110±2.5 ohms.
Rated value 4WD:
- F point: 1.5±0.5 ohm.
- Point E: 55±1.5 ohms.
Make sure the resistance value changes smoothly as the float moves slowly between point F (highest) and point E (inferior).
Checking the stroke of the fuel level sensor float
Move the float and measure height A at point F (highest) and B at point E (inferior) when the float arm touches the stop.
Rated value
Thermistor
Connect fuel level sensor (thermistor) to the battery through the test lamp (12V - 3.4W). Submerge 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 taken out of 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 70°C water and measure the resistance.
Rated value: 104±13.5 ohms.
After checking, apply the specified sealant around the threads of the coolant temperature sensor.
Sealant Name: 3M Adhesive Nut Locking No. 4171 or equivalent.
Add coolant.
