IG Key : ON
Actual value for evaluation
Engine warm up to approx. 80℃(176℉), engine idling
Check items with the scantool
Injector current data by the scantool
Specification
Injector operating booster voltage : above 70V
Injector injection quantity will be changed by the engine load
☞ CURRENT DATA
At the start of injection, a high pickup current is applied to the injector so that the solenoid valve opens quickly. As soon as the nozzle has opened completely, the energizing current is reduced to a lower holding value. The fuel injection is terminated when the solenoid valve is no longer triggered and closes as a result.
IS INJECTOR CURRENT DATA DISPLAYED PROPERLY ?
YES
Fault is intermittent caused by poor contact in the sensor’s and/or ECM’s connector or was repaired and ECM memory was not cleared.
Check for intermittent fault by observing the data parameter for a sudden change while wiggling the wiring and tapping lightly on the suspect component.
Be careful not to damage wires or components during the test.
Repair as necessary and go to " Verification of Vehicle Repair " procedure
NO
Go to " W/Harness Inspection " procedure.
