2.There should be continuity when the float is raised, while there is no continuity when it is lowered.
3.Replace the water level sensor if it is faulty.

1.Connect the circuit tester
to the water level sensor. 2.There should be continuity when the float is raised, while there is no continuity when it is lowered. 3.Replace the water level sensor if it is faulty. |
FUEL LINE HEATER CONTINUITY CHECK <VEHICLES FOR COLD ZONE> |
 |
1.Connect a hand vacuum pump
to the outlet port of the fuel filter pump, and plug the
inlet port as shown. 2.Connect the circuit tester to the fuel line heater connector. 3.Using hand vacuum pump apply a vacuum to the fuel filter pump body, check that there is a continuity between terminals when the pressure becomes -31 ± 5 kPa or less. 4.Lower the load gradually and become -18 ± 5 kPa, check that there is no continuity. 5.The fuel line heater is normal if the conditions 3 and 4 above are satisfied. 6.Replace the fuel filter pump if defective. |
