Production plant : Toyota Motor Corporation
License plate number: Adventurer E-VCV10
Engine grades : 3VZ-FE type
Production year: 1992
Mileage : 77000km
Failure Symptoms: can not start the engine flameout .
Troubleshooting : the fact that the engine can not start from the basic checks begin . After basic checks , the results did not harvest. Remove the spark plug , the spark plug with a thin adhesive layer of gasoline, if ignition systems. Are AUTEL MaxiSYS Pro recognized when the lights mounted on the ignition spark timing light does blink , indicating that the ignition spark. So in the end there is no ignition spark it in the cylinder ?
To confirm that there are no ignition spark inside the cylinder , the cylinder pressure conditions simulated spark test , for which the central disconnect high voltage cables, the cable from the left cylinder head 10mm, 10mm air gap that is done to keep the spark test , the results of the spark is normal. High voltage cable and then pull each uobd2 cylinder spark test results in the air gap of 10mm only when there is no spark , but there are "black jack , jack popping " sound leakage . Reduce the air gap , there is sparking .
Remove the distributor cap and distributor rotor , where the side of the hole has been burned due to leakage .
In order to track down the real cause of the fault , perform various investigations. The results of the resistance value of the high voltage cable , the reference value is generally a high voltage cable is 16kΩ / m, and this engine is the resistance cummins insite value of the high voltage cable 30kΩ / m or more, some of which reach 32kΩ / m. Secondary circuit resistance increased after ignition coil increases the voltage requirements , resulting in insulation breakdown weaknesses leakage .
High voltage cable disconnection, high-voltage terminal of the ignition coil to the low-voltage terminal leakage, closed magnetic coil becomes open magnetic coil , without leakage to the outside , it is difficult to find .
