Toyota Corolla (E120): Inspection

1. Spark plug

Notice

:

  • never use a wire brush for cleaning.
  • Never attempt to adjust the electrode gap on used spark plug.
  • Spark plug should be replaced every 192,000 km (120,000 miles).

  1. Clean the spark plugs.

    Air pressure: below 588 kpa (6.0 Kg/cm2, 85 psi) duration: 20 seconds or less

  1. Check the spark plug for thread damage and insulator damage.

Hint

: if abnormal, replace the spark plug.

Recommended spark plug: sk16r11 (denso made)
ifr5a11 (ngk made)

  1. Check the spark plug electrode gap.

    Electrode gap: 1.1 Mm (0.043 In.)

2. Crank position sensor no.1

  1.  using an ohmmeter, measure the resistance between terminals.

Resistance:
at cold 835 – 1,400 w
at hot 1,060 – 1,645 w

N

otice

: ”cold” and ”hot” on the table express the temperature of the coils themselves. ”Cold” is from –10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).

Hint

: if the resistance is not as specified, replace the crank position sensor no. 1.

3. Crank position sensor

  1.  using an ohmmeter, measure the resistance between terminals.

Resistance:
at cold 1,630 – 2,740 w
at hot 2,065 – 3,225 w

Notice

: ”cold” and ”hot” on the table express the temperature of the coils themselves. ”Cold” is from –10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).

Hint

: if the resistance is not as specified, replace the crank position sensor.

4. Ignition relay

  1. Continuity inspection.
  1. Using an ohmmeter, check that continuity exists between each terminal.

    Specified condition: between terminal 1 and 2 continuity between terminal 3 and 5 no continuity

  2.  using an ohmmeter, check that continuity exists between terminals 3 and 5 when the battery voltage is applied across terminals 1 and 2.
