Fuel Level Sensor Resistance

1. Check that resistance value between terminals 2 and 1 is at the standard value when the fuel level sensor float is between point "F" (highest) and point "E" (lowest).
Standard value:
- Point "F": 3 ± 0.8 ohm
- Point "E": 110 ± 2.5 ohm
2. Check that resistance value changes smoothly when the float moves slowly between point "F" (highest) and point "E" (lowest).
3. If all checks are correct, go to fuel level sensor float height check. If any check is not correct, replace the fuel level sensor.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
