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.

    Circuit description
    The crankshaft position sensor (ne signal) consists of a magnet, iron core and pickup coil. The ne signal plate (crankshaft position sensor plate) has 34 teeth and is installed on the crankshaft. The ne signal sensor generates 34 signals for each engine revolution. This sensor monitors a p ...

    Inspection procedure
    Hint: read freeze frame data using the hand–held tester or the obd ii scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, th ...
