  5. Is the measured voltage within specification?

    YES 

    • Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector. Or, ECM memory was not cleared after repair. Thoroughly check connectors for looseness, poor connection, ending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR ."

    NO 

NOTE: * When handling ELCM and its components, be careful not to damage them. If you drop them on the floor or apply shock to them, it may cause an internal damage. If so, do not use the component(s).
* When conducting Smoke Test to detect a leak in the evaporative emission system, do not implement Smoke Leak Test. Oil used for the Smoke Leak Test can have a vane installed inside the vacuum pump stuck and thus cause a fault.
