Toyota Corolla (E120) 2002–2008 Repair Manual / Ignition / Inspection
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).
- Clean the spark plugs.
Air pressure: below 588 kpa (6.0 Kg/cm2, 85 psi) duration: 20 seconds or less
- 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)
- Check the spark plug electrode gap.
Electrode gap: 1.1 Mm (0.043 In.)
2. Crank position sensor no.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
- 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
- Continuity inspection.
- 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
- using an ohmmeter, check that continuity exists between terminals 3 and 5 when the battery voltage is applied across terminals 1 and 2.
Other materials:
On–vehicle inspection
1. Inspect drive belt
Visually check the belt for excessive wear, frayed cords,
etc.
If any defect is found, replace the drive belt.
Hint:
cracks on the rib side of a belt are considered acceptable. If the
missing chunks from the ribs are found on the belt, it should be
replaced.
