MIXTURE ADJUSTING SCREW (VARIABLE RESISTOR) CHECK <VEHICLES FOR GENERAL EXPORT>




1.Disconnect the variable resistor connector.
2.Use a circuit tester to measure the resistance between terminal No. 1 and No. 3 of the variable resistor connector.
Standard value: 3.5 - 6.5 kΩ

3.Connect the circuit tester between the terminal No. 1 and No. 2.
4.Check that the resistance changes smoothly when the adjusting screw is rotated by the special tool MAS screwdriver (MD998299).
5.Inspect the body for crack or other damage.
6.If any defect is found, replace the variable resistor as an assembly.
