INJECTOR SOLENOID VALVE SYSTEM BREAKING












1. CHECK THE RESISTANCE BETWEEN TERMINALS.
1. Turn the starter switch to "LOCK" and connect the signal check harness.
2. Disconnect the signal check harness connector on the ECU side.
3. Measure the resistance between the terminals of ECU connector (vehicle harness side).







Standard: Less than 2 ohms












4. This is ECU failure or defective contact of the connector. Restore all connectors and start the engine.
5. Erase the DTC.
6. Check the current failure. If the same DTC is displayed, replace ECU. If there is no DTC, then the connector contact would have been defective. As long as no DTC is displayed, there is no problem.
7. Disconnect the injector connector that is located at the front side of the cam housing.







8. Measure the resistance between the pins of the injector connector (male) at the cam housing side.







Standard: Less than 2 ohms












9. Dismount the head cover.
10. Disconnect the injector connector (injector side) of the cylinder displayed by DTC. Measure the resistance between the pins.

Standard: 0.35 - 0.55 ohms at 20 °C {68 °F}












11. Remove the injector terminal cap of the cylinder display by DTC. Measure the insulation resistance between terminal and injector body.
Standard: More than 10 Mohms
