Vehicle checks
1. Ignition coil and spark plugs.
A) Read diagnostic codes.
Note: If a diagnostic code is present, follow the appropriate troubleshooting procedures.
b) Neoplasm check.
Remove the ignition coil.
Remove spark plugs.
Install the ignition coils with connectors connected to the spark plugs.
Disconnect the injector connectors.
Close the spark plugs to ground.
Turn the engine over with the starter to check for sparks.
Note:
- Check the grounding of the electrode.
- If the ignition coil is struck or dropped, replace it with a new one.
- Do not crank the engine with the starter for more than 2 seconds.
- Close the spark plugs.
- Install the ignition coil with switch.
Component Check
1. Spark plugs.
A) Clean spark plugs.
- Pressure: no more than 588 kPa for 20 seconds
b) Check for damage to threads and insulator. If there is damage, the spark plug must be replaced.
Recommended spark plugs
V) Check the gap between the electrodes.
Rated Clearance:
- EJ Series - 0.8 -0.9 mm
- KZ series - 1.0- 1.1 mm
Note: if the gap does not correspond to the nominal value, adjust it by bending the side electrode.
4. (EJ-series) Crankshaft position sensor.
Check the resistance between the connector pins.
- Rated resistance (at 20°C) — 1100+150 Ohm
5. (EJ-series) Camshaft position sensor.
Check the resistance between the connector pins.
- Rated resistance (at 20°C) — 1100+150 Ohm
6. (KZ series) Crankshaft position sensor.
Check the resistance between the connector pins.
- Rated resistance (at 20°C) — 2150±300 Ohm
7. (KZ series) Camshaft position sensor.
Check the resistance between the connector pins.
