Ignition system [Toyota Duet M100]

On-car checks

1. Ignition coil and spark plugs.

a) Read diagnostic codes.

Note: If a diagnostic code is present, perform the appropriate troubleshooting procedures.

b) Checking the neoplasm.

Remove the ignition coil.

Remove the spark plugs.

Install the ignition coils with the connectors connected to the spark plugs.

The original can be read on the website toyotaman.ru

Disconnect the injector connectors.

Short the spark plug to ground.

Turn the engine over with the starter to make sure that sparks are produced.

Note:

• Check the reliability of the electrode grounding.
• If the ignition coil is hit or dropped, replace it with a new one.
• Do not crank the engine with the starter for more than 2 seconds.
• Tighten the spark plugs.
• Install the ignition coil with the commutator.

Checking components

1. Spark plugs.

a) Clean the spark plugs.

• Pressure: no more than 588 kPa for 20 seconds

b) Make sure there is no damage to the threads and insulator. If there is any damage, the spark plug must be replaced.

Recommended spark plugs



c) Check the gap between the electrodes.



Nominal clearance:

• EJ Series - 0.8 -0.9 mm
• Series KZ - 1.0-1.1 mm

Note: If the gap does not correspond to the nominal value, adjust it by bending the side electrode.

• Nominal resistance (at 20°C) — 1100+150 Ohm

5. (EJ Series) Camshaft Position Sensor.

Check the resistance between the connector terminals.

• Nominal resistance (at 20°C) — 1100+150 Ohm

6. (KZ series) Crankshaft position sensor.



Check the resistance between the connector terminals.

• Nominal resistance (at 20°C) - 2150 ±300 Ohm

7. (KZ series) Camshaft position sensor.

Check the resistance between the connector terminals.

• Nominal resistance (at 20°C) - 2150 ±300 Ohm
