Change in resistance between terminals
1. Disconnect the connector from the injector.
2. Measure the resistance between the terminals.
Nominal value: 13-16 Ohm (at 20°C)
3. Connect the injector connector.
Checking the spray pattern of the injector and the tightness of the injector
1. According to the following procedure, release the residual pressure from the fuel line to prevent fuel splashing.
2. Remove the injector.
3. Assemble the special tool as shown in the figure.
4. Apply battery voltage to terminal No. 2 of the three-pin service connector of the fuel pump, as shown in the figure, and turn on the fuel pump.
5. Activate the injector and check the quality of fuel atomization from the injector. The condition of the injector is satisfactory if the injector produces a normal spray.
6. Disconnect the wires from the injector connector terminals and check for leaks (sprayer and shut-off needle) injectors.
Norm: 1 drop or less per minute
7. Connect the wires from the battery terminals to the injector terminals without turning on the fuel pump. Then, after the fuel spray from the injector has stopped, disconnect the special tool and return the injector to its original position.
