ON-VEHICLE INSPECTION
INSPECT SPARK TEST
1. | Remove the spark plug cable.
2. | Using a spark plug socket, remove the spark plug.
3. | Install the spark plugs to each spark plug cable.
4. | Ground the spark plugs.
5. | Check if spark occurs while engine is being cranked.
To prevent gasoline from being injected from injectors during this test, disconnect the injector connectors. Be sure to clean away DTC codes the timing is complete after.
6. | Using a spark plug socket, install the spark plugs.
7. | Install the spark plug cable.
INSPECT SPARK PLUG AND SPARK PLUG CABLE
1. | Remove the spark plug cable(A).
When removing the spark plug cable, pull on the spark plug cable boot (not the cable), as it may be damaged.
2. | Using a spark plug socket, remove the spark plug(B).
Be careful that no contaminats enter through the spark plug holes.
3. | Inspect the electrodes(A) and ceramic insulator(B). INSPECTION FO ELECTRODES
CONDITION | DARK DEPOSITS | WHITE DEPOSITS
DESCRIPTION |
- | Fuel mixture too rich
- | Low air intake
- | Fuel mixture too lean
- | Advanced ignition timing
- | Insufficient plug tightening
4. | Check the electrode gap(A).
Standard (New) 1.0~1.1 mm (0.039~0.043 in.)
5. | Carefully remove the spark plug cable by pulling on the rubber boots(A). Check the condition of the spark plug cable terminals(B), If any terminal is corroded, clean it, and if it's broken or distorted, replace the spark plug cable.
6. | Connect the ohmmeter probes and measure resistance.
RESISTANCE : 5.6KΩ/m ± 20%
7. | Resistance should not be higher than 2.6kΩ per meter of cable. If resistance is higher, replace the cable.
INSPECT IGNITION COIL
1. | Measure the primary coil resistance between terminals 1, 2 and 1,3.
Standard value : 0.58Ω ± 10%
2. | Measure the secondary coil resistance between the high-voltage terminal for the No.1 and No.4 cylinders, and between the high-voltage terminals for the No.2 and No.3 cylinders.
Standard value : 8.8kΩ ± 15%
Be sure, when measuring the resistnace of the secondary coil, to disconnect the connector of the ignition coil.
1. | Measurement of the primary coil resistance Measure the resistance between connector terminals 1 and 2 (the coils at the No.3 and No.6 cylinder sides) fo the ignition coil, and between terminals 2 and 4 (the coils at the No.2 and No.5 cylinder sides), and between terminals 2 and 3 (the coils at the No.1 and No. 4 cylinder sides).
2. | Measurement of the secondary coil resistance Measure the resistance between the high-voltage terminal for the No.3 and No.6 cylinders, between the high-voltage terminals for the No.1 and No.4 cylinders and between the high-voltage terminals for the No.2 and No.5 cylinders.
When measuring the resistance of the secondary coil, be sure to disconnect the connector of the ignition coil.
