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.

Dtc check/clear
1. Dtc check (normal mode)
Notice:
hand–held tester only:
when the diagnostic system is switched from the normal
mode to the check mode, all the dtcs and freeze frame
data recorded in the normal mode will be erased. So before
switching modes, always check the dtcs and freeze frame
data, and ...
Vehicle load limits
Vehicle load limits include total load capacity, seating capacity, towing
capacity and cargo capacity.
◆ Total load capacity (vehicle capacity weight):
Total load capacity means the combined weight of occupants, cargo and luggage.
◆ Seating capacity: 5 occupants (Front 2, Rear 3)
S ...
Safe Exit Assist
The safe exit assist is a system
that uses rear side
radar sensors installed on
the inner side of the rear
bumper to help occupants
judge if an approaching
vehicle or bicycle may collide
with a door when opening
it or cancel opening of
the door, to reduce the possibility
of a collision.
