Toyota RAV4 (XA40) 2013-2018 Service Manual: On-vehicle inspection

  1. Check ignition coil assembly and perform spark test

Notice:

in this section, the terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10 to 50°c (14 to 122°f). "Hot" means approximately 50 to 100°c (122 to 212°f).

  1. Check the dtcs.

Notice:

If a dtc is present, perform troubleshooting in accordance with the procedure for that dtc.

  1. Check that sparks occur.
  1. Remove the no. 1 Engine cover.
  2. Remove the bolt and ignition coil.
  3. Using a 16 mm spark plug wrench, remove the spark plug.

  1. Install the spark plug into the ignition coil, and then connect the ignition coil connectors.
  2. Ground the spark plug.
  3. Check that sparks occur at the spark plug while the engine is being cranked.

Notice:

If sparks do not occur, perform the spark test.

  1. Using a 16 mm plug wrench, install the spark plug.

Torque: 25 n*m (254 kgf*cm, 18 ft.*Lbf)

  1. Install the ignition coil with the bolt.

Torque: 9.0 N*m (92 kgf*cm, 80 in.*Lbf)

  1. Connect the 4 fuel injector connectors.
  2. Install the no. 1 Engine cover.
  1. Spark test flow chart.
  1. Check that the ignition coil connector is securely connected.

Result


  1. Perform the spark test on each ignition coil.

    1. Replace the ignition coil with a normal one.

    2. Perform the spark test again.

Result


  1. Check the power supply to the ignition coil.

1. Disconnect the ignition coil connector.

2. Turn the ignition switch on.

3. Measure the voltage of the wire harness side connector.

  1. Using a megohmmeter, measure the insulation resistance

Standard insulation resistance: 10 m  or more


Hint:

  1. Alternative inspection method:
  1. Quickly accelerate the engine to 4,000 rpm 5 times.
  2. Remove the spark plug.
  3. Visually check the spark plug.

    If the electrode is dry, the spark plug is functioning properly. If the electrode is damp, proceed to the next step.

  1. Check the spark plug for any damage on its threads and insulator.

If there is damage, replace the spark plug.

Recommended spark plug


  1. Check the spark plug electrode gap.

Maximum electrode gap for used spark plug: 1.3 Mm (0.051 In.)

If the gap is greater than the maximum, replace the spark plug.

Electrode gap for new spark plug: 1.0 To 1.1 Mm (0.039 To 0.043 In.)

  1. Clean the spark plugs.

If the electrode has traces of wet carbon, clean the electrode with a spark plug cleaner and then dry it.

Standard air pressure: 588 kpa (6 kgf*cm2, 85 psi)

Standard duration: 20 seconds or less

Hint:

Only use the spark plug cleaner when the electrode is free of oil. If the electrode has traces of oil, use gasoline to clean off the oil before using the spark plug cleaner.
