Fuel Level Sensor Resistance

Check that resistance value between the fuel gauge terminal and ground terminal is at the standard value when the fuel level sensor float is between point "F" (highest) and point "E" (lowest).
1. Standard value:
  - Point "F": 1.0 - 2.0 ohms
  - Point "E": 53.5 - 56.5 ohms
Check that resistance value changes smoothly when the float moves slowly between point "F" (highest) and point "E" (lowest).
If all checks are correct, go to fuel level sensor float height check. If any check is not correct, replace the fuel level sensor.
